Lebron X USA Low

So I had picked up a pair of Lebron X Low USA colorway in a size 12 on a great deal. Turns out they run small and I need to get size 13. I was wondering what people think is a normal price for these since you can't really find them anywhere. I checked on Ebay and they were goin for $220 which seems kind of steep. Is that a fair price or is that people on Ebay just trying to get lucky and by that I mean get more for them than they are really worth.
