At the time I searched, simplygames.com had the lowest price for the (PC) game I was after. I purchased the download code version, paid via PayPal, and received the activation code in my Inbox within just a few minutes. Activated the code via Steam, downloaded it from there too, all worked perfectly.
I can genuinely recommend these guys, they offer digital downloads at very reasonable prices. It's exactly the same product, from exactly the same distributor even, just without the hefty price hike the mainstream distributors tag on - which ludicrously makes d2d titles usually cost around the same as buying a boxed copy.
Will definitely use this service again!
