The shrewd arithmetic behind the various promotions of the merchant

Many businesses will be staged to do promotions, such as "Buy xx xx", "Second Cup Half-price", or "package mail Oh, pro" and so on, so that consumers feel that there is a cheap to occupy. But behind the promotion, who accounted for the cheap, in fact, is not intuitive to appear so simple.

Buy m gift N discount rate

The shell net Netizen "Rachel" is a university finance department undergraduate student, she in "The Nutshell Net" on the post, first will "buy m to give N" as the analysis case.

The so-called "buy M gift n", is the most commonly used in supermarkets a promotional method, the main feature is that consumers buy goods and received goods to maintain homogeneity. For example, buy 5 bags of a brand 125 ml of plain yogurt, received 1 bags of the same brand, the same capacity, the same taste of yogurt.

The discount rate for this promotion method is also best calculated.

When the number of goods (i.e. m) purchased by the consumer is the same, the number of items received (ie, n) is more, the higher the discount rate, the greater the consumers "take advantage of". If, conversely, N is the same, the higher the M value, the lower the discount rate, the smaller the consumer "takes advantage of".

In supermarket, the most commonly seen is "buy m send 1" (only consider m not more than 10), the equivalent discount rate between 50 percent to 90 percent. If consumers receive more than 1 of the goods, it is generally necessary to buy twice times the gift of goods. For example, "Buy 5 send 2" or "Buy 7 send 3", in which case the equivalent discount rate is around 70 percent. So in addition to buy 1 to send 1 special cases, generally buy m send n discount rate is more than 70 percent.

"Layla" assumes that the cost of the goods is half the price, substituting p for the prices, and the cost is C, so c=0.5p. Merchants do a 70 percent promotion, promotional before the product can sell m pieces, sales after the sale of n pieces. In this way, before the promotion, the Merchant's profit is 0.5PXM. And 70 percent promotions, the price into 0.7p, minus 0.5p cost, a single piece of profit into 0.2p, so, the merchant's profit is 0.2PXN. Can be calculated, as long as 2n>;5m, that is, sales after the sale of the original sales of more than 2.5 times times, the merchant has an additional profit.

It's worth noting that bundling and discounting are fundamentally different: in bundled sales, consumers must buy more to get the discount. In the ordinary discount promotions, buy a few are 70 percent dozen, consumers do not need to expand their own consumption, want to buy as much as how much. But in bundled sales, consumers will have to buy more than 2-3 or more if they want to get an equivalent discount of 70 percent. The benefits of this approach are much lower than the same discount rate.

In addition to "buy M gift n", consumers in supermarkets will often encounter "bundled sales." "Rachel" thinks, "buy M gift n" is a merchant clearance tail goods, "bundled sales" is the usual trick to push new products.

For example, XX brand push boutique combination set or buy XX series to send samples. This combination of preferential ways can be subdivided into no gifts and there are two kinds of gifts. For gift-giving products, we can treat the gift as another item. So whether there is a gift or no gift, we can calculate and compare the combined price and the combination of the price of the internal products, it is possible to calculate the equivalent discount rate, to determine whether cost-effective.

Take shampoo for example. A brand of compliant shampoo 200ml is 19.5 yuan, the same series 200ml hair conditioner price is 19.5 yuan, if the purchase of two kinds of need 19.5+19.5=39 yuan, but the combination of price as long as 37 yuan. The equivalent discount rate is only 37/39=94.8%, which is 95 percent.

Second half half-price profit way

The second half price is Half-price, is the food and beverage enterprise promotion commonly used way, especially those fast-food enterprise, in sells the beverage and the ice cream time, often with "Second Cup Half-price" as the selling point.

The magic second Half-price gives people a seductive impression of "the second is 50 percent," and "Rachel" calculates that the actual discount price is only (1+0.5)/2=0.75, or 75 percent.

A cup of 9 yuan of drinks to sell 6.8 yuan seems to have no attraction, but the second Cup as long as 4.5 yuan sounds a lot of music, the key is the resulting sales for businesses to bring profits far more than the cost of concessions.

Suppose, a cup of ice cream price 10.8 yuan, the cost is 3 yuan, the purchaser can buy freely kerfuffle.

No second half price: set to sell M cup ice cream, the merchant's profit is (10.8-3) xm=7.8m.

There is a second Cup half-price: set to sell n cups of ice cream, business profits for (10.8-3) x (N/2) + (5.4-3) x (N/2) =5.1n.

After the second half price concession, as long as sales can be improved, businesses can expand profits.

And the actual situation, may not have "Rachel" calculation so simple. In practice, even if the Second Cup half-price, the sale of the N Cup of ice cream, it will not be all the time to buy two cups this situation. There are quite a few customers who choose to buy only one Cup, after all, not everyone really needs two cups of ice cream. So businesses will still enjoy the "no second Cup Half-price" profit, 5.1n is only likely to appear the smallest profit.

Generally speaking, take the second half price of this bundled sales of goods to fast food and small commodities mainly, the cost is not high, as long as sales can rise, businesses can have more profit.

"Layla," said: "In fact, all of the bundling is to use the consumer's psychological, of course, there is no bad, after all, the business in most cases still let, although they may actually be more money." This through the profit-driven sales to obtain greater profits of the promotion method, to consumers also bring a lot of benefits. And the only thing to consider is, do you really need to buy so much?

The mystery of xx yuan minus xxx yuan

Every time the festival arrives, the major shopping malls will be wildly promoted. In order to attract customers, merchants will launch a variety of promotional means, of which, "xxx yuan when xxx yuan flower", "full xxx yuan minus xx Yuan" is a more common discount method. However, what is the difference between the two strategies? The shell net "Netizen" The believer of Tesla, remind, in anxious pay money, may want to make clear before buying later.

First, let's take a look at the discount strategies that businesses use. The so-called "xxx when xxx Yuan Hua", such as "44 when 99 Flower", is to spend 44 yuan to buy 99 yuan of shopping coupons, and then in the shopping malls with shopping coupons consumption. For example, to buy a pair of shoes priced at 1091 yuan, you can spend 11 44 yuan to buy 11 99 yuan Shopping coupons, offset 1089 yuan, and then cash out to pay the remaining 2 yuan. At this time, the actual payment of 486 yuan. In terms of a formula:

For a commodity with a price of P, set p=99n+m, where m and n are integers

Consumers need to pay p1=44n+m yuan

However, if http://www.aliyun.com/zixun/aggregation/31945.html "> m is close to 99, we actually have a way to save money." For example, you can certainly buy 11 99 yuan of shopping coupons plus 90 yuan to buy a price is 1179 yuan of clothes, then you spent 574 yuan. However, if you buy 12 tickets 99 yuan, then you only need to spend 528 yuan, and after the purchase of clothing coupons will be left with 9 yuan (of course, this 9 yuan will not be for you).

In other words, when the m>;44, that is, the commodity price close to 99 of the integer times, to buy more than a shopping voucher strategy more cost-effective. At this point, you need to spend p2=44 (n) dollars.

Again, the so-called "full xxx yuan minus xx yuan", if "99 minus 55", in the purchase value of 99 yuan of goods, when the checkout to subtract 55 yuan, that is to say, the actual consumption of 44 yuan. Or a pair of shoes priced at 1091 yuan for example, because it "full" 11 99 (1089 yuan), so need to subtract 11 55 (550 yuan), Consumers pay 11 44 (484 yuan), plus 2 dollars in the difference, which means that the actual payment of 486 yuan can be.

In terms of a formula:

For a commodity with a price of P, set p=99n+m, where m and n are integers

Consumer need to pay p1= (99-55) n+m yuan

This looks very tempting, but careful observation is not difficult to find, "full xxx yuan minus xx yuan" promotional strategies to make it easier for businesses to control prices to achieve less. At this point as long as the price of goods m from 99 closer the better. This will not only ensure that the customer discount rate for only one item is at the highest point, but also that the discount rate for customers buying multiple items won't fall too much.

"Mail Oh, kiss" easy to win the impression points

"Mail Oh, kiss!" In the era of e-commerce, consumers often choose to pay for a particular item because of the famous quote. Logistics costs may not be a burden for most people, but it is the desire of the majority to dispense with the cost of logistics.

The "Tesla believers", through the data, unravel the economic rationale behind the "package". To buy strong customers without express fee is actually to reduce prices, which seems to be more favorable to consumers, but in fact, the package of mail for businesses more favorable.

For example, the courier fee of 10 yuan, full 50 yuan on the package of the strategy to the consumer's feeling is as long as they buy more than 50 yuan, the merchant for their own pay 10 yuan courier fees. But the reality is that originally the net buys all trades to express, but the merchant for the Express company, actually also is the purchasing power strong customer, therefore the courier company also will give the merchant the corresponding preferential, therefore has the larger scale net shop single time express cost will be far less than 10 yuan, for example may be 5 yuan. In this way, businesses to spend less than 50 yuan customers charge 10 dollars, earn 5 yuan, and the consumption of more than 50 of the customer package mail, even if the loss of 5 yuan, the actual oneself may not pay not to earn, but to give customers a favorable impression of 10 yuan, and finally molded a "package of Oh, pro" traditional virtues.
