I read this book very well today.
Free product: any product that prompts you to buy other complementary products. Free object: everyone who will make the purchase.
Walmart's latest popular DVDs are only for $15, all of which are for sale to attract customers. The company tempted you to go in by offering a DVD at a lower price than the cost. After you go in, they can sell you a washing machine, which is profitable. Restaurants often subsidize expensive wines with cheap food; the original "free lunch" appeared in Los Angeles at the end of the 19th century, but it was just free for customers who had at least ordered a bottle of beer. Regardless of the product or service package, the price of a single product or service is often determined by the consumer psychology rather than the cost from the bank's financial plan to the mobile phone consumption plan. Your telecom service provider doesn't rely on your monthly minute (monthly minutes) to make money-its price is low, because it knows that when you take a mobile phone, you will need it for the first time-but your monthly voice mail service is a huge benefit.
I think that I received a text message of 10086 today: "I paid 100 yuan before the 31st day, And I will receive a 30 yuan bill at the end of next month." In fact, this is a free price, prompting you to spend money. When you have enough balance in your phone bill, your mind changes.
This free learning is very important when it comes to internet startups. The development of the software industry, if still rely on products to sell prices, will be very stupid, but also wrong practices.
