Why do you buy things you don't need?

70 percent discount on the most beautiful (and usually very expensive) shoes in the world! One problem: they are a size too small. But you still have no doubts, it's now or never! And so you buy them. The sales are back in the country! Do you also give in to every minus X percent or are you a tough aunt who can say "no" to all those bargains? If you are the first type, you have probably regretted returning home from your conquest. How come? That we suddenly no longer seem to think rationally when we are shopping? Lieve Douce - marketing expert from Hasselt University - says that it is not only up to you, but also up to the stores that use the ideal seduction strategies.
