Limited supply of 20 percent off iTunes gift cards

An eBay seller has iTunes gift cards for 20 percent off, with a limited quantity available.

The deal, available here, sets a price of $40 for $50 iTunes gift cards. These are good for the U.S. iTunes store only.

It amounts to a 20 percent discount on iTunes purchases, with the difference, of course, being that you are paying up front for the purchase. The deal has a purchase limit of three iTunes Gift Cards per eBay user ID, while supplies last.

Here is how the eBay deal is described.

Give the gift of one-stop entertainment. Each card includes a code redeemable for music, movies, TV shows, games, apps, and more on the iTunes Store, the iBookstore, the App Store, and the Mac App Store. Recipients can acess their content on an iPod, iPad, or iPhone, and watch or listen on a computer - Mac or PC.

We can attest to the fact that at the time of this writing, this particular eBay deal is still live.

All the items sold are plastic gift cards, as the vendor is unable to email customers the gift card number or numbers at this time. However, the description says that customers should look out for the feature to be allowed in the future.

Shipping is free for the gift cards purchased in the deal. All gift cards are shipped using USPS Critical Mail. For those unaware, as were we, Critical Mail was launched in January of 2011.

To qualify to use Critical Mail, shippers must have a customer commitment agreement with the United States Postal Service and mail 5,000 or more Critical Mail letters and / or flats during a single calendar year.

Critical Mail is charged one price across all destination zones regardless of weight — $3.50 for letters and $4.25 for larger flat-sized envelopes. Critical Mail is a sub class of Priority Mail®, and is available for automation-compatible letters and flats.

According to the eBay deal, all items sold -- again, as of this writing -- are estimated to arrive between Fri. Sep. 27 and Thu. Oct. 3
