I know im a little late to the party but i just ordered new wheels from AM today so ive been all through there policies... They only process orderes monday - friday before 4pm est. If you ordered it early sat morning it most likely wasnt processed and shipped untill today (monday). If you got the 2 day shipping I would put my money on Wednesday it being there.. Also within a couple hours of ordereing I recieved an e-mail from them including UPS tracking number so you can know for sure what day it will come. However if they processed your order today then you prolly got the e-mail today. I clipped this from there shipping policy page hope it helps and gl.
