Thats strange, I have never had an issue over the years with RUI.
Sometimes usps take a while to get it in there system even when its on its way. once i had an order (not form rui, was supps) never show up in tracking yet I got it to my door.
maybe its a tracking issue on there end and not the order itself?
either way RUI will take care of you and I assure you you will get your order.
They have NEVER seen them screw anyone over from all the years I have been on this forum.
