Through Monday, Costco is discounting iTunes gift cards 20% again.
The rebate limit is 15. I guess there’s some universe where you need more than $1500 in iTunes cards. If you do, just pay for the first batch and get in line again. Keep in mind Costco Executive Club members get an extra 2% rebate here as well. This deal is valid through November 30, 2015.
With all the promos I’ve seen on iTunes gift cards the last 6 months, you’d be foolish to pay face value. Seems like there’s always some opportunity to get these cards discounted, though 20% is about the max i see.
