overcharge.
He thought he "had to pay" $75 to get a firearm transferred.
correct me if i'm wrong, but you can't overcharge someone who is will to pay that price. the "going rate" is determined by the buyer, not the seller.
i liken it to buying Art. there is the price that the artist/gallery will ask or have marked on a piece. if you just want it, you'll pay that price and establish the "going rate"...like MSRP
the fact that someone else would ask for a discount and receive it (usually starting at 40-50%) is simply a reward for their additional effort of researching the market first.
the seller was just selling the item for what each buyer was willing to pay.
the first buyer wasn't "gouged", he paid what he was willing to pay for the item...so did the 2nd buyer
