People love sales and tend to buy a lot more stuff, video games included, during big sales. One of the most famous sales for PC gamers is the big Steam Sales. There are 4 of them during the year, but the summer sale and the Christmas sale are the biggest. During that time, we often see games at 25%, 33%, 50%, and even 75% sometimes. So this question arises: what's the sweet spot? It's logical to assume that the greater the discount, the more it will sell, but I kinda assume it's not a linear function. So what's the best discount in your opinion?
