When you call and give them a part number, they will tell you the price and ask how many you want. They're very nice people to deal with, if you don't want it just say so, they'll say OK and ask for you next part number.
Yeah, really, what a racket. Only time I ever buy eBay parts is when they're upgraded in some way or if Crosman is out of stock. I really dig the barrel I got for my 1322, though... the guy did a superb crown on it and modded the loading port. It actually outperforms my LW. I believe his eBay name is behavingstrangely.
