I keep trying to buy stuff but it just keeps telling me that my "shopping cart has expired". I've tried refreshing, removing and re-adding items, changing browsers, but I still keep getting the error. Any help?

It has been happening to a lot of people for hours. I don't know why, tho. They haven't said anything

This still seems to be an issue,cause i have the same problem.

Glad to see I'm not the only one. I guess the marketplace is down. Hopefully they get it fixed soon.

Same problem here.  Usually problems like this (people can't spend money on your products) are given top priority.  Hopefully it will be fixed soon.

Just happened to me trying to buy the Vecna Bundle
