I've loved grocery stores my whole life (weird, innit?), and have made quite the game out of saving money in them. But prices are zooming so bad, I go in and look around and don't know whether to laugh or cry at the crazy price tags.
If you think about it, save for some canned goods and some incidentals like small appliances, EVERYTHING in a grocery store is going bad, minute by minute. So they are always going to run some sales to clear a category, a particular brand will run a sale to push product, etc. Here in Nashville, most of the 'Weekly Ads' come out on Wednesday and run through next Tuesday, whether Kroger, Publix, or local mom and pops (yours truly NEVER goes to WalMart). So any time there's a really good sale or a buy one/get one for packaged goods (nothing that needs refrigeration or fruit/vegetables), I stock up and stick them back.
Coffee, pasta, oils, rice, beans, etc. The store has to move it now, or write it off, and that's when it's my turn to save.
Of course we have the 'organic' stores, Whole Check Market, Sprouts, etc., but with all the farms around here, not much point. Actually, the best produce are several of the large Mexican or Asian markets here in town. Besides, you can't get yucca fries or good pho at the Hot Line at Kroger !
Fruits and vegetables are mostly buy now/eat now, and then there's meat. It's only two of us and the best deals are these 'Family Packs' but what are two older folks who are light eaters do with that many chicken wings, chops, etc.?
So I bought a vacuum sealer, divvy every thing up to meal amounts, date them, and vac'd they'll keep for months with no freezer burn. They thaw out beautifully, and there's dinner.
It's the one game I can play with my money (I DON'T gamble) that I usually always come out to the good.
