I ordered my Calmini bumper from xterraparts.com about 3 1/2 years ago....ordered on friday and it was delivered by freight on monday. Sliders took a whole 5 days. It just depends if the product is sitting there on a shelf ready to ship. The hot vendor seems to be Shrocks, but i've yet to have an issue from my Calmini products (bumper, sliders, steering system). Like others have said, just play the waiting game. I almost waited a week for my 3" suspension lift.....almost.
