It's easy to ignore your budget when it comes to holiday shopping. Yes, there are the presents that you end up buying for everyone (along with those sale finds for yourself), but there are the other big and little things that add up: Shipping gifts, travel costs, groceries for parties, etc. So really, it's safe to say that most of us go beyond our budgets. When that's the case, it can be hard trying to justify loading up on decorations. After all, they are seasonal. You have to store them. And there are lots of tacky things out there.
