Depends on how they shipped it, and how much their transfer fee is.
Transfer fees can range from 10 bucks or so to 50 depending on the FFL. Shipping on a handgun can range from 15-20 bucks for USPS (FFL's can ship handguns this way but regular folk can't) to 50-60 bucks for UPS overnight air (the way you as an individual would have to ship it.)
57 bucks total is within reason given the circumstances.
This is one reason that I keep my handgun selling/trading local these days.
I shipped my Ruger SP101 to a member here from Midwest Firearms in East Peoria, and all together I paid 57.00 dollars to have it shipped to Texas. Is that right?
