The Steam Summer sale is pretty much an annual thing, and you can almost time your watch by it, but it's still nice to have confirmation that bargain are incoming. We've just received a tip stating that Valve is looking for all potential games for the Steam Summer Sale to be submitted before June 13. So the sale could, theoretically, start any time after that date.
In other words, when the calendar strikes June 13, your purses and wallets have permission to start trembling.
Time to start planning that budget people. Stay safe out there. Video games are important but food and shelter is also important. Start pawning your wedding rings and whatnot. It's almost go time.
