My sister-in-law has always done all her grocery shopping at Wal-mart (or Sam's Club). Wal-mart accepts regular coupons, but I don't think they double them. They have lower 'everyday' prices on items, but they never do buy-one-get-one or other deals like grocery stores do. If you don't want to do any work or mess with coupons, and your purchasing is based on what you need at the moment regardless of price, then you'll do better at Wal-mart.
My S-I-L recently decided to try couponing, because other people had been suggesting it. I think she went to Kroger. She got a bunch of canned tomatoes for 16 cents apiece, and some other items.
Don't you imagine Kroger prefers her to be in their store, doing that, instead of continuing to spend her money at Wal-mart?
Of course.
Mrs WBill and I clip coupons. Not to PJ's extreme, but I'm not afraid to double up on store brand and manufacturer's, and hit the BOGO's and Loss Leaders, and so on. I figure that we get 1-1/2 weeks of groceries free, every month.
I'm still dropping a hundred bucks (or so) a week in the grocery store. They're not complaining about that. And, for every "Loss Leader" that I'm taking advantage of, there are are more "high margin" products that I'm sure that I'm buying. Simply because, for instance, if I want "hot dogs", they're not on sale (and I don't have coupons), it makes no sense for me to drive to another store that might have then on sale, just to save that extra $1.50. So, I just pay the mark up.
I use to do most of my grocery shopping at Wal-Mart, until they REMOVED the fabric department, I’d do the groceries when I went for fabric. Their loss for being STUPID, because I’m not the only quilter that did the same. Kroger’s was 5 blocks closer plus I earn fuel points and can get 10 cents a gal off at least 1 tank of gas, usually 2 per month.
Now I do 95% of my grocery shopping at Kroger’s which doubles my coupons up to 60 cents. And honors the BOGO coupons.
