Here's a pic from the gift card aisle in the store advertising the deal:



Also, note that I picked up a flyer that was advertising the spend $75 get $10 coupon deal, so I could finally read the fine print. The fine print has a bunch of exclusions on what can count towards that $75, among them are beer, liquor, and gift cards. So, there's no compatibility with this offer and that. Whats more, you have to spend $75 after applying all discounts and other coupons. So, this a solid spending of $75 on groceries to get that $10 coupon. If you need to spend that much anyway, then perhaps it's worth it. On the other hand, why not buy 7 or 8 of those gift cards with your 5% card, and then break up that $75 order into 7 or 8 smaller orders, and get it for nearly free net of your coupons?

No. The $10 coupon is $10 off your purchase of $10 (or more). Believe me, I've been breaking up everything I buy into ~$10 batches for the past week. As a side benefit, my arithmetic skills have been given some extra exercise as well.
