Bitcoin has never really been used to purchase goods, because the point is that people don't want to use a tool for purchasing stuff that goes up significantly afterwards. In the same way, it can go down significantly as well. In this case people won't mind having spent their coins if the price goes down afterwards, but what if the price goes down before you purchase something? You either need to add more BTC to purchase the same goods, or you just don't buy it anymore. People aren't interested in such inconveniences...
