Consignment is a good process for selling a firearm with little to no headache as long as the service fee is not a ripoff. I would never pretend to tell an LGS how to run their business but I think that the service charge should be stairstepped or a flat fee based upon value - a $300 gun and a $1000 gun will take (about) the same effort to sell - 20% fee for the $300 gun produces a $60 return while the $1000 gun produces $200 return - same labor, same overhead, same 4473, etc. I don’t buy the argument that “I have rent, electric, insurance, labor, etc - those are fixed costs whether my gun is there or not - you are never told “Hey 10% is fine by me, I have none of my money tied up in your gun, your sale ROI is just about 100% profit.
Anyway, my point is do not be afraid to negotiate if the LGS is accommodating - a consignment deal is usually much, much more lucrative for an LGS than an inventory sale. Remember, it is your money until you decide to release it.
