Offer ends Saturday 8/5/2017 (stated by employee tho I saw a twitter screen shot)
Applies to only $25, $30, and $50 gift cards.
You have to buy one full price, then the second one is 20% off, so you net 10% off (sorry if I was not clear).
Thought I'd post this since I didn't see it.. It's not the best deal, but better then nothing, especially if you don't have a costco membership... would post a link but can't find the ad online, called the store to make sure it was live.
