I added about 10 games into my shopping cart, then I wanted to add some money to my steam wallet and had some credit card issues. After I solved the issues and added money to my wallet, I was back to the steam homepage and went to open my shopping cart.
However, there were no games in the shopping cart and I do not remember some of the games I added. Is there a solution or trick? I tried to look at my browser history and go back to the shopping cart but still no games appear.
