I ordered mine from walmart online. Approx 131 each. Rims were more expensive than the second best price I found online. But throw in the Free shipping I ordered and received them with 3 weeks. The date code was approx 2 months old.
Had them mounted at tire warehouse. I have put zero miles on them.
They must order them by the container and probably ship them out quickly.
I also ordered valve stems from them. The delivery date was over a month out. I called and complained received a ten dollar credit. Ended up ordering from Amazon.
