I'll be the first to admit that I don't do a lot of shopping around when it comes to grocery purchases. I live in an area where there just aren't many choices. I can buy groceries at the commissary, a tiny local store that charges A LOT (which I still use occasionally because I like supporting our local economy), the four or five stores in Minot that are owned by the same people, or the Super Walmart. There are a few groceries available at Target, CVS, and KMart, and that's pretty much the extent of my options. I DO look through the ads of every local store on Sundays or Mondays to see what the best deals are, and if it's a really good deal, I try to stop by whichever store when I'm in the area. Or I send my husband to the store with a specific list (there's something he thinks he needs at Menards almost every week anyway, so he's already in Minot regularly).
Since I've started to get more into coupons, I've found that I'm pretty jealous of people that have a lot of options. I've always been thankful that I have the option to shop at the commissary, but the more I look around, the more I realize that other people can get deals just as good at their local stores (assuming they have competition) if they really watch the sales and compare prices.
Like for instance, this week by going to a couple of different stores my sister can get a 48 load bottle of laundry detergent for $.99 after a $1 coupon, and some full size tubes of toothpaste that will be free after the $1 coupons she has. I don't think I've ever been able to score that good of a deal on either of those things at the commissary, without counting overage from another coupon!
