as far as i've seen, they're not discounted. plus you have to buy the whole kit of 4, even if you need just 1. this happened to me when a car scraped into my car and bent the molding but luckily not the fender sheet metal.
I picked mine up for $260 at one of the warehouseparts joints. And it was a no-brainer to swap them out when I realized I'd screwed up and ordered the 2012 edition of them instead of the 2013's.
