Shipping is the killer and deal breaker on big parts. If you have a swap meet around your area, I would suggest that or putting ads on the Craigslist in your region.
if you can ship just the wheels its not bad. ups has a box thats perfect size (for the 14s) you just have to cut it down just a tad shorter. put a wheel in then a piece of cardboard ( for protection)in between then the other wheel. but no matter what ship two in one box and it was around 50$ to ship.
so it was around 100.00 to ship 4 wheels pretty much cross country
