Virtually all US flashcart vendors that supported paypal have more or less shut down due to being raided, account frozen by paypal or whatever combination of the two or whatever other reason not specified. If your looking to get them shut down as well, you seem to be doing a pretty good effort at it.
No, they are not scammers. I had no problems ordering from them before.
Hey bud saw that you had posted in my topic I wanna say since the whole thing went down nds-card.com has come back and given me a full refund. So as for their authenticity they at least are showing they are sorry for what went down. So that being said this is still an option since they do also have a LOT of good reviews as well. I wont be recommending any other sites however as so many ppl thought the reasoning behind my video was to discredit them for my own make believe reselling business. I will however tell you this any site that only accepts visa send them an email and ask them if they in fact take virtual visa and with that there are sights that you can buy virtual visa cards with Paypal funds as for the security behind it the virtual visa is still funded behind a banking system so it might be a lot more hoops you have to jump through to get a chargeback if something fishy does happen. However from my lesson learned after this en-devour if something does happen remain calm and patient and talk to the company in a calm collected manner and try to work out between each other a fair conclusion.
nds-card is not on the Sky3DS official resellers, I've seen a thread that says they've been scammed (Billski's), a thread saying their CC was compromised after using the site, and their transaction is not secure according to Zaide. Um.
