From New Year's Day to the present, home appliance stores have been continuously promoted, and sales of prototypes have also been involved in the two-month promotion period. In order to sell the prototype in hand and make room for new products, price reduction is also essential. The author knows that the price of home appliance is only 5 to 8 percent of the new machine. Many consumers are willing to Low-cost prototype pays. However, many consumers do not know that while the merchants are discounting the prototype, the after-sales service is also facing a discount. Ms. Zhang is a typical example of “hidden rules†for purchasing prototypes.

Self-paid maintenance fee Ms. Zhang was "hidden rules"
Ms. Zhang purchased a 42-inch domestic LCD TV in August 2009. The original price was 7,500 yuan, and the prototype processing price was 5,800 yuan. According to the sales staff at the time, the TV was only placed in the store for three months, and the quality of the product had no effect, because the picture was cheaper and Ms. Zhang bought it. Ms. Zhang did not pay attention to the payment at the time, and the salesperson indicated the words “prototype†on the invoice. 
When the TV was just moved home, everything was normal. When the blue screen began to appear in December 2010, Ms. Zhang immediately contacted the after-sales department of the product. The maintenance personnel quickly came to the door and found the reason for the blue screen, but it was unexpected that the maintenance personnel Ms. Zhang told me that because this product is a prototype, it can only be guaranteed for one year, so the cost of repairs needs to be paid separately, and the cost is about 500 yuan. Ms. Zhang was very angry and thought that she was deceived and continued to use the after-sales service theory. After several times, she was in vain. In the end, she could only pay 500 yuan for maintenance.
There are still many cases like Ms. Zhang, who are eager to buy prototypes because they are cheap, and neglect the after-sales service of products. It seems to be more than a thousand yuan cheaper, but the maintenance costs paid for failures during use are far more than the savings. Next, we will look at the situation that Ms. Huang has encountered, and I will know the "catty" hidden in the sales of home appliance prototypes.
