who said I couldn't read? I know exactly what the ad is for.
So like I said no one is going to give him $600 for 2 wheels. 2-3 wheels go for cheap due people looking for a complete set of wheels and settling for having to find and additional 1-2 wheels, selling one wheel usually goes high due to someone needing just one wheel, and sets are self explanatory. Example, I bought 3 of those 22's I had for $200 and had to pay $300 for the final one.
