wow, that's some muddy advertising. since they put a $300 limit it on it, i would assume you can get as much as $30 off. make sure to ask a manager before ringing up.
I did go there today. I was able to buy 2 preset @ $25 gc & 4 that I set the amount, all in the same transaction. And I got $5 off every $50 spent. Add in the Visa reward, its like getting 11% off.
The ad states that this deal ends today, Dec. 7. I got this deal today! You had to get the Disney GCs in increments of $50.00 to get $5.00 off each one, but I got $300 (which was the limit) in gift cards for $270! Great deal!
