How does everyone feel about the trading cards thing being integrated into the sale? I thought that getting the cards and any other dealies was predicated on spending, but I just got the first card today.

Tip for people who want to partake but not go crazy - go to a store where you can get a Steam Wallet gift card, buy it in the amount that you are ok spending, then go home and put the gift card into your account. If the game you've been waiting for shows up in a flash sale or something, you've got funds to cover it, but when you've emptied your wallet, you're done. I do this with Steam and with iTunes and it works out really well - even if my general cashflow isn't great, when I plan ahead and have money set aside, I can still partake in sales.
