Yeah, it's tough to sell a used muzzleloader. I purchased a new stainless steel Knight Disc a few seasons ago from Natchez, and spent around $200 shipped.
I thought I could get at least $125 for mystainless Wolverine...nope.
I sighted it in and hunted only once with it, taking a nice 8-point, butit was used.

My buddy ended up buying it from me for $100, but I included the scope &rings.
His daughter put it to good use and killed2 does and asmallbuckon her first hunt.
