There is nothing easier than using your shopping cart - on the product page of the game you wish to buy, you can find a friendly green button called Add to Cart.
To avoid accidental duplicate purchases you can't add the same game to your cart more than once. However you can just purchase it again straight away after you've bought it.
We're working on an easy to use gift feature, but in the mean time you can simply send the activation key along to your friend by email or in a beautiful Birthday card ;)
If the lucky friend has a Gamesplanet account, pop us an email and we can transfer the game from your account to his :)
