A couple of of things to note here. I don't think he was trying to buy it with cash, so while I may be right about people not being able to cart a members only release depending on when they canceled their membership, it could also be another issue with cashing in credits.
Here are some things that I discovered while trying to help, though. The first is that, with the new shopify checkout, you can now switch up the shipping address on individual orders and it shouldn't fuck up your whole account... theoretically. Of course, with all of the VMP shipping errors, this might be risky. Another thing I discovered after typing in their shipping address in Switzerland is that it wasn't going to charge me for international shipping. It even clearly stated it was giving me free international shipping. Obviously crazy, but a good find.
The last thing to note for anyone offering to help is that this person isn't really offering to provide anything in exchange for doing this and paying for their record out of your own pocket -- you're doing someone a favor is every sense of the word, including taking on all risks without benefit. I told him that, if he just wanted to paypal me the 28 bucks, I'd order it for him, since the post stated he was just trying to, understandably, avoid buying a 3 month membership to purchase it. It turns out that he doesn't want to spend any money at all and was just hoping to use his year old credit. The credit is not in addition to reimbursement for what you laid out, it IS the reinbursement. So, rather than simply buying yourself a record, like you could do -- and probably would have done, if you really wanted/planned to -- you would be purchasing a stranger a record and, only after the fact, they would offer to purchase and send you a record using their credit, which would partially need to be used on shipping, since they don't have a membership anymore. Plus, if you're like me and the record you would have chosen would have been King Krule anyway, and the only reason you haven't purchased it is because you're trying not to spend money on anything else right now, they couldn't even order that for you for the very reason this whole thing started in the first place. And, again, you could just buy the album for yourself without the hassle.
