Is it a gimmick or a real discount for the decoration company to accept the model house?

It is certain that the decoration company wants to collect model houses. As for whether it is really necessary to give discounts from time to time, it depends on the situation. Some are purely gimmicks, and some really have big discounts. I still suggest that you don't care too much about discounts. After all, the decoration still depends on the quality. If the quality, technology and after-sales links are not good, the discount is meaningless. Discounts are just icing on the cake.
