I hope it's not coming USPS, they are slower than a herd of turtles lately...
I've had stuff coming from them sit for 3 - 4 days in my regional distribution center... One package went from my regional center to loop around to Des Moines, IA, and then back to my regional distribution center in Chicago 5 days later while the other 3 boxes sat at the regional center...
I had an order get shipped locally here that shipped yesterday get to my front door this afternoon by UPS....
Go with UPS or FedEx if you have a choice, USPS is slower than old people f*ck lately....
