Steam's Russian partner QIWI also mentioned a July 11th sale date. Valve has managed to make something of an institution out of its seasonal sales, with many waiting their arrival.
In some cases people have been known to save their wads of cash just for these moments to snap up games they've wanted, but didn't want to pay launch price.
Apparently QIWIto use their payment service to deposit some funds in their Steam wallets ready for July 11th sales. It has also been noted that the Midweek Madness deals end early this week. The evidence mounts!
Remember to direct your employer to pay Steam directly this month; it saves on hassle.
