Ever since last years big eBay sale of $50 iTunes cards for $35 I've been holding out for a similar 30% off deal. This Costco deal is only 15% off so not enough for me (yet others will like and appreciate it).
Since it's 84.49. That would actually be 15.51% off. With an executive membership you're actually looking at paying 82.80 (since you get 2% back with your executive membership). So it'll end up being 17.2% off.
Wow, and just like I said earlier, Paypal (its digital-gift website) had a 50% off iTunes gift cards until finally selling out 3.5 hours later. I bought $100 worth before they stopped me from buying any more.
