Will card prices go up after the sale?

Sell them and buy cheap games for money from them :P

I'd say the sooner you sell stuff the better. As times passes, more people get cards. Therefore the prices drop. I remember selling Summer Sale cards for 0,30 Euro and more the first days. Now they go for half.

bhahahaha, two threads about this with 10 seconds difference... epic.

Well, I think it will go up, especially if they don't turn them into mystery cards again. I'm holding on to them for sure.

Well, I doubt they'll get any cheaper after the summer sale so I think it worth to wait and see.

well after the sale ends you can still craft the badge but there will be no more summer card drops so i would imagine so

If you're talking about the SSS cards - the prices will rise.

Talking about cards overall, not only SSS

I sure as hell hope so, I got the fucking Prison Architect card three times xD

Cards in general? No. They will keep dropping.

Summer sale cards? Depends, if they are unique to THIS sale event and there will never be any more? Then yeah, if a few years they'll probably be worth more, but not much, there are simply too many of them.

Sell them while you can get a little bit for them. Dimes add up, once you sell 8 cards from one game, 5 from another, etc.
