Can no longer sell items on Steam community market

Yes.

one game a year...
Every once in a while some game will be on sale for like 10 cents or something... just grab that

Fantastic...
Does anybody know the current cheapest game on steam?

I just bought a game as a gift, it doesn't count. So I have to buy it to add to library?

thats a longggggg time not to be able to mess with the market, i make a killing on there

Damn that's bad, D: i don't usually put money or buy games in steam

Just buy one of those under 25 cents game every few months, that'll keep your Steam market active and without problem~

Rather easily done by selling cards you've farmed off games, really, you don't need to put money into your wallet at all, except for the fist time unlocking the market. From then on just sell cards and every few months buy some cheapo few cents game.

Yeah. That is bullshit.

It may be an error. Check Steam forums. Had that happen to me during Christmas even though I'd definitely made purchases within the year, possibly due to using an alt on mobile, where the alt has not purchased anything in over a year (no real causes for the error that I'm aware of, but that's my best guess regarding anything that may have changed).
The main fix I've read about is to install a demo or a free game. I'm not 100% certain that that's what fixed it for me, but everything worked fine again after doing that.

Edit: and now I'm realizing I'm replying to a necro'd thread... thanks, necromancer.
