One mistake I've made in the past, and maybe you have, too, is to spend my refund money on things that I would like to have instead of things I truly need. Another idea is to take that money and NOT spend it, but rather invest it in some sort of retirement fund, kids' education fund, etc. However, if the refund is burning a hole in your pocket and you simply have to buy something, I understand. But let me tell you what to buy or not to buy in April. Why? Because if you wait just a little while, you can get better deals.
