Try deleting your old mail… I have had that problem before. The items are delivered via mail
Correct. We just “resolved” an issue for an ArenaNet employee who wasn’t aware that there is a limit of 10 mails in your GW account. (Not counting NPC and event mails, that is.) So please reduce your store of mails and I just bet that purchase drops into your box real soon!
If you continue to have issues, even after clearing your mailbox, please contact Support by filing a ticket through the “Ask a Question” tab on that linked page.
