It sounds like a transhipper operating out of Oregon.
Happened to me selling a pair of LS3/5a to a mainlaind Chinese scammer. Paypal address was Oregon and months later he complained about slight color difference between crossover PCB (heck they were made in 1970s!) and asked me to give full refund PLUS shipping from mainland CHINA! Took almost 5 months for paypal/eBay to settle, thankfully in my case it was in my favor as I DID send him pics BEFORE shipping via ebay messages of the speakers inside out and 360 degrees.
