When you are looking through your coupons or checking out those ads don't buy something just cause it's a good deal or free. Only cut and use coupons that you will use! I think this is very important, when I started using coupons and found deals that were hard to pass up I could get them. I noticed I had things in my home that I would NEVER use. I had to give the items away, gift them or donate them, which is a good thing to do but at that time in my life I didn't need the "clutter".
It is hard, very hard for me and some people to pass on the free items. I get so stinking excited when I get that awesome deal and wanted to tell everyone but come on really how much time does someone want to spend looking for coupons and shopping at a million different stores anyway? So I have learned to pass on thing I don't need.
