It was through GTR Garage. Shipping through USPS was the only option he gave me. When I get home I'll take a look at the shipping label to see when it was actually shipped. Not sure how long it took to get from the original seller to GTR Garage plus they had to dismount the tires before they could ship the wheels. Those could be reasons why it took a little longer. But yeah, couldn't be happier with the service!

EDIT: The boxes were postmarked on Oct 20 and arrived on the 27th so it took a week to ship and that's counting the weekend. So they must've taken their sweet time with it over in Japan.
