Thanks, Sharptater & FishDonkey, for posting your find and also results. I just received my seeds a few days ago from The Vault. Here's a breakdown of my experience...
I already mentioned how much of a pain it was trying to use a couple of the methods available other than cash (bitcoin & wire transfer). I ended up sending them cash, international registered mail. The mailing part cost $14, which isn't too bad. They will help you beyond extent, by the way, via email. They're very helpful and responsive as far as customer service. I'm sure there are over 30 emails in the thread between us during this process. They ship very fast also. It was supposed to take 7-10 business days for my cash to get to them, but within that time they had already received my letter and mailed out the seeds. They threw in a couple extras. Packaging was extremely legit and safe. I paid an extra $10 I believe for them to send them in individual 'displays' from the growers. So the process ended up taking somewhere around 10 days. Not bad at all.
And the quality part... I germinated 6 seeds from 4 different growers/breeders. Every single one was healthy looking and germinated perfectly. So they get 5 stars in my book for quality, customer service, speedy shipping, and trust (because I sent cash).
They also mentioned a few times that they're working hard to get the 'credit cards from the U.S.' issue taken care of.
