I'm going to Bed Bath & Beyond. I have some money left on a gift card, and yesterday got a 20% coupon off my purchase, so I may as well go and spend it on the items I need (some garbage bag and a new back brush for the shower).
Pro tip: BB&B is extremely generous with its coupons. You can bring in a bunch at a time, you can bring in outdated ones, and they'll all be honored. At least that's what I've been told and in my experience. I get them in the mail and in newspaper ads but don't go there that often, so I let them pile up and then take them in all at once. I used to throw out the out of date ones but now I take those in, too.
I mean, if you have two 20% off coupons and you only buy one thing, they'll just use one. If you have one coupon and buy three things, they'll spread the 20% over all three things (I think). But if you have three things and three coupons, you'll get 20% on all three (again, I think).
