Valve's yearly Steam Summer Sale should be kicking off next month, and while the company never officially announces any exact dates beforehand, sticking to tradition, the sale date and time frame may have already leaked out.
Multiple sources have confirmed to Steam Database that the massive sale will begin on June 25 at 10am PT, with it slated to run for two weeks as usual. SteamCN has also unearthed the same time frame, and leaks regarding Steam sales generally tend to be correct.
Amongst smaller promotions scattered throughout, Steam holds two major storewide sales a year, so this may be a good time to start updating wishlists and preparing wallets considering missing this would mean waiting for the winter sale in December.
Also, don't forget that the Steam Spring Sale should be opening its doors later this month, but for those waiting for deeper discounts, it's probably a good idea to hold out until the much bigger summer sale comes online.
