From 9to5Toys.com:

.

For a limited time, Walmart.com is offering a $100 downloadable Apple iTunes/App Store gift card for just $80. These popular gift cards can be used on iBooks, iTunes Movies, Videos, music, Mac and iOS Apps.  We’ve heard these do work internationally if paid for with a US source and used in the US iTunes/App Stores.

You are basically getting 20% off every Apple media purchase you make.  Also makes a great gift…we imagine.

Update:

@newsagg well, we posted yesterday morning so it won't THAT fast ;)
