If you are ever unsure if a store allows coupons just ask!
When I moved to island, I was unsure if Bed Bath and Beyond (BBB) took coupons but was amazed by their travel size section. I asked and they said yes they take manufacturer coupons. BBB will price adjust the coupon down to the price of the item, but in many cases you can score free items. Also, they will NOT stack a BBB coupon with a manufacturer coupon. BBB will take competitor coupons, like Yankee Candle Coupons, but will NOT stack with a Bed Bath & Beyond Coupon
Bed Bath & Beyond does price match but will not allow you to use a coupon in conjunction with price matching.
