As far as I understood, you need to wait for real sales (when there is a countdown timer on top of page). This website appears to be on sale 365 days a year, but that's not the case; when there is no sale, you are still seeing sale prices because you have CGTrader credits balance. I'm guessing you are putting many things in the cart and everything appears with sale price. Once your credit balance runs out, you are paying the normal price for the model. So always check your CGTrader credits balance, so you know how much discount you can expect (1 credit = 1 usd). There are items that are on sale 365 days (flash sale), they are marked with a green bolt sign.
