Funny you mention that... I stopped in Fletchers today just to get a lay of the land and I inquired about the transfer fee. I think for a brick and mortar 50 bucks is more than fair. I am happy to pay it to support their business. When I called their store late last week, a courteous and helpful person answered the phone. They gave me the email address of the person who handles their transfers. In less than one business day, they got the EE seller what they needed to ship. Responsiveness costs money, people cost money, and a good customer experience commands a good buck. They earned my business last week, they earned more of my business today.
Other than this most recent purchase from an individual on EE, I typically buy from Sportsmans Outdoor Superstore and have it shipped to my IL (former) FFL. SOS prices are almost always 200-300 lower that what a local gun store can do price wise for the same piece. If I know I am saving hundreds on the cost of the piece, the transfer fee of 50 bucks is small taters.
Just my .02 folks, happy to be here... :)
