Glad this came up, I had the same problem. I bought a prepaid "NON-greendot" visa gift card specifically for this purpose, and I couldn't use it on either of the two good seedbanks, I read carefully on the back, and it states "this card is issued by MetaBank pursuant to a licence from Visa" or in other words, not a strait up visa gift card like I wanted, and they can put whatever BS rules they feel like on the card. Learning this, I tried to buy a regular vise gift card like I used to be able to find. Turns out, they won't LET you buy a different gift card with a gift card, but they never told me that, just stayed at "processing" for a week until I called to check on it, then I had to wait days for the money to be returned to the first card before I could buy other stuff. But when I called I did end up asking about why I can't buy stuff online, because that's why I wanted a new card, and after putting me on hold he said "because of new federal laws" I can't purchase internationally with giftcards, some BS about financing evil or something. So I tried searching for these "new federal laws" online and found zip, except for the stuff about new regulations making sure the customer isn't getting fee'd to death and other stuff, but NOTHING about buying internationally with giftcards, not one word, so I have a feeling they are just screwing over the little guy with self-imposed new rules, not the fed's rules, but still blaming the new rules that actually protect consumers, and why? To build grassroots(no pun intended) support against the new rules that card companies hate, by lying about which rules are which. Scheming bastards. Well they aren't fooling me, and I'm never buying a giftcard like that again, not unless I'm CERTAIN they can be used "all over the world" like the packaging claims. I don't want a greendot either, just more fee's. I can load a friends greendot though, he gave me permission, so hopefully that goes smoothly. One other thing I though of, if they give me any guff about why I want to buy internationally, I have the perfect "say no more" excuse for them, "japanese adult novelty items" and they shut right up.
