<human>: This literally just happened... So we are sitting here, we got nothing to play, well, we got like 300 games in our library but nothing is fun anymore. We browse the summer sale and we found H1Z1 to 50% off. I already got it but he didn't so I suggest this to him. "I can sell all my CSGO skins so I can buy it for you, and you have to repay me later this month?" We both agree and I head in to my inventory. I start selling the shit I don't use, nor care about to see if I get enough money to buy it. After awhile, I had to remove some skins from the market and re-sell them and lower the price. Then all my skins are gone, nothing but a Galil Sandstorm left. While this was happening we talked about how much fun we were going to have with this game, I told him some stories when I played it and we got really excited. Finally I get enough money to buy it, we were happy... Until I went to the front page and the Steam Summer Sale was over... Fuck me...

Can you summarize the given text in a few sentences?
<bot>: I sold every skin in my inventory to buy H1Z1 to a friend, but the summer sale was over when I was done
