Friendly reminder: Never buy anything during a Steam sale until it is featured as a Daily Deal, Flash Sale, or Community's Choice. The aforementioned 50% discount will almost certainly be increased to 75% for a select period of time. Check back often (or probably check this thread, I imagine someone will notify everyone) and get what you want at its cheapest.
Of course, if what you want doesn't hit DD/FS/CC, get it on the last day. No harm done.
what is this "bison" dlc?
any links?A file that was found on the Steam databases. All we know for sure about it so far is that it's in the DLC section and it's called "Bison". Seeing as it still hasn't been officially announced yet I doubt it'll be available before Christmas now - let alone on sale. Chances are we'll be hearing more about it in the new year.
