Only thing for sure is the buy 1 get 1 30% off iTunes gift cards.
Just wanted to mention, I buy the iTunes cards at Walgreens every year. They have buy $30 in iTunes cards and get a $10 Walgreens gift card. I buy enough to pay for DS's apple music for a year and then use the Walgreens gift cards to buy Steam or PlayStation gift cards.
I think they are also offering the $10 Walgreens gift card with $50 iTunes purchase this year, but that's not as good of deal.
