For my shopping at Costco I typically stick to the bulk items that are usually involved with cooking, and try to take advantage of their coupons whenever possible. If you don't get the coupons mailed to your house, the membership desk usually has extras. Ask to be put on the mailing list next time you are there!
Coupons for pure maple syrup are few and far between, making deals very rare. Trader Joe’s maple syrup is of equal quality but sells for 67¢ per ounce. My local discount grocer, Winco Foods, sells pure maple syrup for 55¢ per ounce. Bottom line: no other competition comes close. I always buy my pure maple syrup at Costco.
Costco’s canola oil cooking spray is so much cheaper than competitor prices, I don’t even mess with coupons or shopping around. I just pick up a pack of these every year or two, and I know I’m getting a deal.
