Hi A., a few months ago I ran into a single mom buying groceries at Wal-Mart. She had a LOT of coupons and told me how she saves a bundle of money each week. Apparently, when she was a newlywed someone taught her a system for making them work for her and she swore by her system. I keep meaning to try it but here are a few things I remember:
1. Most coupons come out about three weeks before those items go on sale. She kept an envelope/file where she put each Sunday's coupons--the SECRET was to postdate the envelope for three weeks in the future. Just before that date she pulled that envelope out to shop; by then the item was often on sale. (She had worked in a grocery and said there's a shelf life for many things and almost everything goes on sale sooner or later)
2. She said it's hard to find stores that still double or triple coupons but they're out there (Randall's? Kroger?). She knew which days were double and triple days and shopped then. Also, her mom or aunt shopped at an different grocery and told her when there were sales worth noting.
3. I asked who had the best prices and she said it had to be Wal-Mart.
4. She also mentioned some of the drug stores and their deals (like the CVS card; I have one but rarely shop there)
Someone mentioned Groupon and I love that one. Subscribe for your city at www.groupon.com and watch; each day there is a different deal for that day. Our favorite thing is being able to try different restaurants, often at half price! For example, you might buy a groupon for $15 but it's worth $30 or more at the restaurant. We have had wonderful luck using groupons with no trouble. Once one of the ones we bought went out of business but groupon e-mailed me and offered to refund or credit me. They have been great that way.
We find the Entertainment Book doesn't work as well for us any more as it used to now that we have a family; however, we ALWAYS made back the money we spent to buy it so it wasn't a bad investment. The problem was that our favorites were never in there!
Another thought regarding anything I need to purchase. I always look online at www.froogle.com. (It's really google shopping) Once there I enter specifically what I need and then search. It's a great way to compare prices and find different sources for the items. Just watch the shipping costs.
Good luck with your studies. You are so smart to be frugal; try also to stay out of debt. Dave Ramsey has lots of good advice about all that at www.DaveRamsey.com. If you listen to his radio show it often doesn't take long to feel better about living wisely!
