I do all my own cooking and only order in food every couple months. I figure that makes up for the fact I get the expensive cuts of meat and fresh berries and the good chocolate. Not to mention the expensive gluten free breads/buns/bagels. Of the things I do like, though, I get multiples when they're on sale and stock up as much as the cupboard will fit.
Clothes, on the other hand, I wear until they fall off me.
