Yeah, I'm getting the exact same thing. Brought one as a present and was going to buy another as a present for someone else, couldn't. Was sad. Not a bad workaround but Thirdup, but it would be nice to know if this was working as intended or a bug.
Just ran into this bug myself. Went to buy a ToB for another char and it is missing from the cstore. Asked around at DS9 and ESD and others said it was still in the cstore.
