You may also notice some weird trading cards in your inventory recently which totally hinted the Steam Summer Sale. And if you participated in the Summer Cleaning, you may notice that there is a little box in your inventory which may be useful in the future sale.
So you’d better get ready for the big sale coming up. We will let you know once it is live.
