I'm not sure - with regards availability I emailed and they said it was not possible to swap a L for a M. Interestingly, I ordered a T-Shirt separately which also seems to have gone missing in the post.
Last week on the store there was definitely the 12" and slip mat available - maybe someone cancelled their order.
Personally, I'm not having much luck with the fulfilment of these drops. For the KoS drop, my order was messed up and I missed out on 2 12" and t-shirt.
Limited drops seems to be the latest trend, but the fulfilment is not great. I managed to order an Unkle Psyence fiction anniversary signed 7" a few weeks ago which "got lost in the post" (i.e. they sold too many). Rant over
