ATTENTION: We have run out of Steam keys for [ blank ].

Not? I just always show them instantly and write them down.
You don't go to a brick store too, buy something and ask them hey would you store this for me for a year?

I think it would have been valuable to have choice of "haven't encountered it" as well to actually see if majority have had to wait or no. Since not every bundle and not every game has had this happen, I have strayed clear of that happening to me for example.

I'm waiting since 09/11/2018 for a key of Meadow. It's not that important, but it wasn't restocked.

I agree there should be an option "It hasn't happened to me yet". Now it seems you're trying to make people think that it's a general issue happening to everyone.

i found out a week or two ago that first class trouble wasn't in stock from the December 22 choices
