I have noticed, in retrospect, that some of eBay sellers, while their listing are targeted to U.S. buyers (based on listing setup), ask for non-U.S. currency to pay, such as Euro or British Pound or Canadian dollar or Aus$. The sold goods are usually electronics. Paypal would automatically convert the US dollar to other hard currency so this is not an issue for any U.S.buyer, but does show seller's not favoring U.S. currency. This has been occurring at least 2 years. Marketplace is really efficient and revealing.
