I had a small kitchen/bathroom reno in my apartment so I was stockpiling a bunch of Home Depot gift cards and wanted to squeeze as much juice as possible. If you are able (ymmv) and want to go the extra step...
Buy the Choice gift card at Target for $100 to get a $10 Target card if you have the circle deal. (additional 5% with Redcard, yeah it worked for the gift card)
Redeem Choice gift card at giftcards.com for the discount. So that initial $100 (or $95 with RD) nets you like an additional $20 or something in discount card and Target card.
I couldn't build a suana shower or viking range kitchen with this, but those extra drops of juice squeeze helped.
