I use credit cards to purchase what I want. Sometimes I'm good and pay it off five seconds after making the purchase, and other times I'm very bad and pay it off months and months later.
I make my purchases in bulk. In the last couple of months I've purchased quite a few handbags and luxury items; my last handbag purchases were at least four years prior.
But I buy other things as well: Cameras, iPods, tech gadgets and gear, watches, etc.
