I disagree. This is way too low.
The going rate for consignment commissions at dealers with decent traffic (that is, not small one man hobby dealers) is usually in the 15% - 25% range. Four Seasons is 18%; 15% on expensive guns or large collections.
The dealer takes no inventory risk; does not have to tie up capital; take a chance on how long it will take the gun to sell; risk have to drop the price below what (s)he expected, etc.
Now, consider what it takes to make sense for a dealer to buy a used gun:
- The consignment percentage
- Additional compensation for tying up and risking capital
- These percentages are off of the wholesale cost to the dealer of a same type new gun, so figure 10% right there (guns run on tight margins, so I'm figuring best case for the person selling to the dealer).
Some conservative guesses:
- baseline % on the no-risk consignment sale: 15%
- discount % to base dealer offer relative to wholesale: 10%
- % to net dealer reasonable ROI on inventory investment: 20%
So, an offer of 55% of selling price is not being unreasonable - it's just a reflection of the reality.
Edited: Interesting how CrackPot and I composed our replies separately and came up with remarkably similar numbers.
