Why the fuck I can't buy steam games ?

Try to restart steam if you have not done that.

Site's fucked up?

Restart Steam, should work.

I tried to buy the game with Steam, steampowered.com, and steam mobile. Nothing, that didn't work :/

Btw, because the steam client sucks hard always use the site for purchases.

Or you could do as it suggest's and contact Steam Support. Chance's are if both the mobile and PC client's and the website are failing to take your purchase, then there is a chance something could be wrong account and/or billing side. Try Steam's Support to find out if there's something wrong there.

That's because too many people are trying to buy Call of Duty at the same time. Steam just can't handle that.

Make sure you didn't change the currency in your browser. (trying to look for prices in different regions) Happened to me once and couldn't buy from the browser anymore. (Altough I could still use Steam itself).

I can buy it for you. :)

try to change your DNS

thats happened to me first time i was trying to buy something on steam

what type of payment you used? if debit card, your card could be blocked.

try contacting your bank support to unlock the restriction

This error means your purchase privileges have been temporarily removed until verified by support. You will have to contact them and answer their questions, usually your name, address, credit card number and the like.

I suspect you either changed your paypal/credit card recently or you bought a lot of games in a short amount of time. This will alert Steams fraud system and you are screwed.

As for the sales, i am sorry to say but you are screwed. They don't care and they will not give you a coupon or anything to make up for the loss.

Merry Christmas

restart steam...or delete system32

...one of those should work

Contact Steam Support
Do You Use Steam Wallet Or CC?

there is more solutions ... i had this problem to ...

1.Delete everything from steam folder EXCEPT STEAMAPPS and STEAM.EXE
OR
2.Change your Cloud country -> This worked for me :) ( i changed the cloud country , and it didn't worked at start ... but in like 10 minutes it worked )

reinstall steam :<

You need to contact steam support. It happened to me twice within 2 weeks. They will ask you to verify your billing info and then will fix it. Sadly, it takes the support a week or so to reply to your ticket which will be too late for your purchase. I'd recommend asking a friend to buy games for you until they fix it.

Are you trying to use a coupon? I got the same error trying to buy Death Rally and Trine 2 with coupons until I figured out that they don't work during the holiday sale.

have you tried to make a new account? and then buy those stuff to gifts for your old account.. it could work

Maybe you're not in the country you're buying it in. I mean when you are in Belgium you can't buy from France store. Sounds weird, but when you try it you get that error.

I tried with another account, nothing... :(

Because you have a dirty mouth.

In all seriousness, I just bought They Bleed Pixels and Half Minute Hero, so the problem's on your end.

You have an account lock, for security reasons, I had that too, contact Steam Support, yeah it sucks when you lose a Deal, I lost one too back then.
