Well guys I think I got burned by Overstock.com. They did indeed ship me a (new) camera, but it appears to be gray market.
There is a sticker over the serial number on the outer packaging that reads "Fujifilm X100T Digital Came...national Model No Warranty) NEW" and the serial number starts with 52Uxxxxx.
Earlier in the day (before I received the camera) I emailed Overstock customer service, and asked if they were an authorized reseller for Fuji. The emailed back and indicated specifically they were an authorized seller for the X100T. I could have went to some no-name place (and saved $$) if I really didn't care about gray market. I bought from a link from the Fuji website, from a seller that was a few bucks cheaper than Adorama, but who I had used before with no issues.
Should I be concerned? What would you do if you were me? Camera appears and accessories appear new, but I haven't unwrapped yet. No US warranty card inside.
EDIT: I was able to register the camera on the Fuji USA website. Not sure how strict the serial number formatting is, however. Can anyone confirm they have an X100T (non-gray market) with a 52Uxxxxx formatted serial number? I saw some posts online from several years ago that indicate US cameras have a xxAxxxxx designator for America, but there is nothing corresponding to U.
