I was doing something similar on Staples. Unfortunately Staples sells only $100 Visa GCs online, and the fee is $6.95. Staples GCs on Cardpool were 6.5% off at first, became 6%, but are now only 4% off. Not so good anymore. And don't foget 5% Shopdiscover for Staples. Unloading a bunch of $100 Visa GCs at Walmart can be a pain though.
