Recently I've noticed that almost every product has a discount offer. I stopped buying for the full price at all Example from yesterday: I had a free version of the product and after a week they offered me a 50% discount for the premium plan. I even wanted to buy it for full price, but then I accidentally checked my e-mail I'm curious now whether all these discounts spoil customers. Probably users even don't buy if there's no discount. Do you make discounts for your product? What are the results?
