Yeah, but for two months prior to the crash, you were making more money than the cost of your products. Since the BTC price was going up, the 24 hour average that SR uses was lower than the current BTC price at any time, and the buyer got charged more BTC (if the price was pegged to the dollar). So not only did you withdraw more BTC, but the price continued to rise until you cashed out, which for some vendors can be a few weeks. Nobody complains when the going is good. Vendors were basically getting bonuses for 2 months, and the BTC crashed in one day, so then they cancelled orders, causing the buyers to lose money.
