Walmart will beam you a $100 Apple iTunes gift card for $80
FORTUNE — If you buy a lot of iPhone apps or iTunes music, Apple AAPL gift certificates are almost as good as cash.
Indeed, there’s a lively trade in iTunes gift cards on eBay EBAY, where a $100 certificate will fetch anywhere from $82 to $109.99 on a Buy It Now basis.
Now, as The Verge notes in its latest “Good Deal” tip, Walmart WMT has entered the market, selling electronically delivered iTunes gift cards for 20% off. There’s no sales tax, no delivery charge, no dealing with sketchy eBay sellers.
The catch is that like any online purchase, you can’t make it without giving Walmart your name, address, e-mail and payment information (PayPal and major credit cards accepted).
