The rumours that have been circulating appear to be true: GameStop are now selling Steam vouchers in $20 and $50 denominations. The vouchers come with codes that you can redeem to add the funds to your Steam wallet. Handy for anyone who doesn't have a credit card, or perhaps who wants to limit their spending on the Summer sales. No news on availability outside of the United States.
