Actually many giftcards (including HD) sell for about face value- sometimes over- on fleabay because a lot of buyers get % back on purchases. They also have no expiration.
I may use this since this has been my hesitation at applying for the SWA business & personal cards (16credit plus $500 giftcards) with $5K spend in 90 days requirement each. (I'm scared of coining Chase and I hate to pay the $150 each BT fee).
