UPDATE: It appears that Target will be repeating this deal again from the 21st July to the 3rd of August!
A big thanks to Jason, Valdemar and Jason for this updated tip.
Just as our last known deal was ending, Target have announced that starting tomorrow (30th June) they will be offering 2x $20 iTunes gift cards for only $30, a popular deal which saves 25%
This deal runs until the 7th July.
Thanks to WardenBrown for this tip.
As a side note, if you are a Mac user and are planning to upgrade to Mac OS X Lion, this is a perfect opportunity to top up your iTunes/AppStore credit and save on the cost of the OS, which will be available exclusively in the Mac App Store sometime in July.
