Both of my sons have shotguns they want to sell. They still think Dad knows everything and they asked for my help. One has a Benelli Camo Nova that has been used maybe twice. It is a 3.5" 12ga. The other is a Remngton 11-87 3" 12 Ga in camo. I'm guessing this weapon is 7-8 years old. Both have all choke tubes plus the Remington has a couple aftermarket tubes.
Try to evaluate the condition....be very critical..... Then search Calguns.net or Cabela's gun library for comparison...... deduct 10% from what you think is fair and post here on BD........ Just a suggestion.......
That isn't a problem..... You find a licensed gun dealer near you......... they ship the gun to a licensed gun dealer near the buyer.... it's usually $35.00 - $50.00 You can negotiate the dealer fees........ The internet is your friend.........
