I received my code almost immediately after placing my order. Due to my own misunderstanding I attempted to use the key in the "wallet" section of Steam instead of adding the game via the "plus" symbol. I wrote cdkeys and received a response back right away. Although there was still a bit of confusion between myself and cdkeys, I had an email in my box with clarification before the day was over. I absolutely recommend this site after my purchase. The process is relatively easy with a confirmation text/phone call required for authentication. And, the quick and engaged responses with technical support is great if needed.
As for the game, I own Fallout 4 on console and enjoyed playing it a lot. Due to a shift at work requiring me to begin traveling a lot more, I decided to pick it up to take with me. I love the addition of mods and the flexibility that they provide. I would also like to say that I have this up and running on a Surface Book with the Intel chip on it and even with mods installed, I'm getting roughly 30 FPS across the board. 30 is not great, but it is very playable.
Given my experience with this site and assistance in getting my game up and running, I returned to purchase the Season Pass also and had a flawless experience in that transaction also. For anyone on the fence of making a purchase from this site, I'd say you really should consider making the purchase. I would suggest paying attention to the region listed also though. I was going to have a buddy purchase the Fallout Season Pass on here only to realize that the one listed is not for our region for PSN. Here's hoping they get a version for the U.S.
Overall, I'd highly recommend using cdkeys, I'm a happy customer.
