Many of the on-line retailers are actually all part of LKQ (the wallmart of auto dismantling it seems) so they all get their inventory from the same place. Be sure to actually speak to a human and verify that the parts are really in-stock. I went round and round trying to get one of my wheels a couple years ago.
Another thing I found - all my wheels (they all came from LKQ even though I bought from 2 different vendors and shopped every one I could find) were 'refurbished'. I wish they weren't. I'm guessing they just did a re-paint (aka 'refurbish') as standard practice. The problem is they did NO prep work - they just sprayed a new coat of paint over the original stuff. Gee, if you don't do any prep work, the new paint doesn't stick well. It started lifting from the first moment I put the lugs on and popped the paint. After that, I was peeling paint off every time I hit them with the hose or car wash. The really crazy part is there doesn't appear to have been any problems with the original paint. I've peeled most of the crappy new paint off and it actually looks better than with the 'new' stuff coming off like a snake shedding it's skin.
I don't know which vendor provided the wheels that peeled the worst and like I said they all actually came from LKQ just though different on-line sites. It hasn't been worth me complaining to the vendors since I bought them specifically to beat up in the rocks anyway, but if you were more worried about looks it would be a problem. Like I said, the paint started to pop and peel as soon as I seated the lugs on one wheel, so it's not like I caused the issue.
On the other hand, the OEM wheels have held up to some real abuse and are still going strong. I'd recommend them in a heartbeat.
