Here’s a great stocking stuffer idea. Walmart has the $50 Google Play Gift Card (Email Delivery) on sale for $40. There is a limit of 2 per customer.
NOTE: Some have had problems with their orders getting canceled. If you have this problem, your IP address is likely on a blacklist for one of several reasons with Walmart. This is not necessarily your fault but Walmart being over cautious with gift card fraud.
HOW TO FIX it:
Call Walmart directly, tell them the issue and they can manually override the order and place your account/credit card on the safe list.
Added bonus: For those that (still) play Clash of Clans, redeeming this card will also get you 25,000,000 gold and elixir free ($100 value).
