Not sure if this is the right place to ask, but I was wary of it and wanted to post here in case anyone deals with similar issues going forward.
A buyer bought a for-parts laptop from me on eBay after haggling the price for like 2 days. Finally made the sale, and the shipping address was routed to a Flybox location in Doral, Florida. I looked up the reviews for this place, and almost every review is about how people make purchases from outside the US, have them shipped there, then forwarded to whatever country they're in (sorta like a proxy shipping service). But all purchases are made from stolen credit cards or with fake information, and sellers mentioned getting hit with "item not received" refund requests, among reports of legit customers having their packages stolen.
I really didn't feel comfortable with it. It just seemed sketchy, and I feel like I dodged a bullet by not putting myself through disputes. I just refunded the buyer and reported it.
