At my closest Safeway in the suburban DC area, the gift card deal had a couple of restrictions.
- Store had a policy of max 4 gift cards or $200 per day on a credit card, 20 gift cards or $2000 per day on a debit card.
- The coupon only rang up twice per Safeway account. My partner was with me so when my third gift card didn't produce a coupon, we switched and did two on his.
So 3 cards on my Safeway number, two by credit with the coupon, one by debit without the coupon, and 2 more cards on my partner's number by credit with the coupon. Not bad but jealous of the poster who did 10 in a single day!
The manager said I could come back daily and see if the two coupons is a per day limit. We'll see if I have the patience.
