The pics are misleading... The cases were in perfect condition and same with the PCB. Dirty as hell but usable if needed... All in all I paid just under $200 to have shipped to the states...
What?? But the listing says their condition is "Seller Refurbished". "Refurbished" means restored to as much like new as possible—in particular,
thoroughly cleaned. That's obviously not true here, and the seller should have listed them as simply "Used".
And you paid nearly
$200 in shipping?? Why? The shipping amount indicated in the listing is $4.47 per board, so it should've been half as much as that. What happened? Did the wrong shipping amount simply appear in your bill? Or did the seller raise it somehow?
I can't tell you what to do—but if a seller did this to me, I'd be mad. I'd take photos of the boards
exactly how I received them, contact the seller, attach the photos, and ask for a partial refund (of an amount you think is fair). They sold you something you didn't receive, and it'll take extra work for you to restore them to that condition.
I'd also request that the excess shipping charges be refunded. There's no reason you should've paid twice as much as the listing said.
By contacting the seller as soon as possible, your complaint is recorded in eBay's system. If the seller doesn't give you a refund within a reasonable amount of time—e.g. 3 business days—you can call eBay and ask them to step in.
Considering the premium prices you paid for these boards, and to have them shipped to you, I wouldn't hesitate to do this. It's your right as an eBay buyer who wanted a fair, open deal.
