Update - Merch shipping
Added 2023-09-24 19:23:24 +0000 UTCA patron has pointed out that you need to provide a shipping address if you want the merch goodies you are rewarded with.
In order to give a Patreon (i.e., you) access to your address / shipping you merch, you have to go into your account settings, account tab, and edit (or add!) your shipping address. Inside of the edit button screen there's a list of patreons that have selected the ability to send merch. Gotta checkmark any new ones (i.e., you) and then save.
I would of thought Patreon would notify you of this but no bother.
Thank to Patron kiTA for the heads up
