I had gone through several days worth of discovery queues during this sale, adding things to my cart. Then, one day my cart was empty, and I lost everything I'd been saving up there.
This reddit post explains how to see games which you've marked as "Not Interested", but I'm looking for games I was interested in enough to put in my cart (and thus didn't bother wishlisting). Is there any way to see this history? Or is it gone for good?
