If you look at that Amazon listing, below the "Sold by" line, there's a link for "10 new
from $305.24". This seat is the first one listed, Condition states "New", sold by Powersport SuperStore.
Then again, I really want to buy this seat, especially at $305. Alas, my Roadcrafter is only three weeks old, so I think I'm done until Christmas (of 2013).
