Ultimate Spider-Man sale at Comixology
Issues #72 to #133 are on sale at $0.99 per issue. Usual price is $1.99. Sale lasts until 11 pm 7/22/2012 EST in N. America and at local evening times in other areas.
I also got a good deal because last week I paid $85 for an $100 iTunes gift card from Walmart. That gave me an even better deal on the comics since they are paid for via my iTunes account.
I just wish I had caught the sale on the earlier issues, 2 weekends ago.
