This week, CVS is running a promotion where you receive $5 in extrabuck rewards if you spend $25 (or more) on iTunes Gift Cards.

While perhaps not as good as Best Buy’s frequent 20% discount, if you are a regular CVS shopper and buy a $25 iTunes card this week with your extrabucks reward card, you’ll receive a 20% rebate back to spend on a future CVS trip.

Since the discount doesn’t scale with the value of the card purchased, you are best off just sticking with a single $25 iTunes card to maximize your savings.

The deal is good Nov 4th through Nov. 10th and is unfortunately limited to one per household.
