They moved more product in a month at normal prices than they normally move in a few months. I doubt they can stock enough product for one year. And then they ran out of product to sell, and it is difficult to get more. They raised prices since because of less volume of product being sold due to demand far outweighing supply.
Just because people bought everything they had to sell doesn't mean they're living like kings. It means they don't have anything left to sell going forward.
