The easiest way I've found to save on the GCs is at Target. We have a Red Card (5%) and get our prescriptions filled at Target. After every 5 Rxs, they mail us an additional 5% coupon. Stack that with the Red Card and you save 9.75% on Disney GCs. As a PP mentioned though, they only have $25 and $50 increments. I did this a few weeks ago and cleared out the $50s and had to get a big stack of $25s too. I think I ended up using 63 GCs to buy our APs.
