Since I started college and took on loads of debt, not much.
Sure, there are things I want to get. Eneloops to replace all of my AA's and AAA's. A dishwasher. A better apartment. A dishwasher. A TV, or else just a bigger computer monitor. And yes, a dishwasher.
But I can't really afford them right now, so I don't shop. And I tend to look for things that I will really use, not just trivial little items.
Speaking of which, it's time to go shopping now - groceries. Oh joy.
