I finally have an excuse to use the shopping cart. I have never touched it. But for some reason, it loses contents between adding then (ShoppingCart.InsertItem) and the redirect to ShoppingCart.aspx. Currnently, I am only trying this anonymously. I can see this items added debugging ShowProduct, but they are gone as soon as ShoppingCart.aspx loads.
Any clues?

Apparently at some point my application stopped storing anonymous profiles. I have no idea why. The web config still says to allow anonymous. Logged in user stuff still works. Roles work. But I noticed I have zero anonymous user. Anyone have any ideas? It used to work because I had to clean up every once in a while.
