Okay, the steam summer sale has arrived in all of its tomfoolery
Standard rules for Steam Sales apply (Taken from reddit.com/r/gamedeals)
Until the last day of the sale (check the countdowns on each game page), DON'T BUY A GAME UNLESS IT'S A DAILY DEAL, FLASH SALE, OR COMMUNITY CHOICE.
If a game is a daily deal, flash sale, or community choice THE PRICE WILL NOT GO LOWER. Additionally, major titles are most likely going to be all three at least once.
