Google's reportedly sending out a $1 coupon to Android users to spend on applications, music and other types of premium content by the end of September, but as usual, there's a caveat: the credit is only available in the United States.

We know, we know. A dollar can't get you much. But if you're a student, for example, on a strict budget and want to treat yourself to a new icon pack, you can without having to worry about the impact it's going to have on your bank account.

If you decide to go down that route, we'd recommend trying out Elun. It's currently on sale for $0.99 and comes bundled with more than 4,100 Full HD icons and 31 stunning cloud-based wallpapers, making it an absolute steal for the price.
