Ever see something in a store that you gotta have? How about those rainbow suspenders you wore only once? Prevent the "wish-I-hadn't"s by asking yourself these questions: *Will I use it or wear it often? *Will I use it or wear it a couple months from now? *If I get it, will I have enough money for what I'm saving for? If the answer to any of these questions is no, you might want to think twice. If you still aren't sure, try waiting a week to see if it has the same appeal.
