Hello! I was in need of some advice on a trade-in I'm planning on doing. I own a Mossberg Maverick 88. I bought it at a gunshow in town awhile back. It's a six shot with a 28 inch barrel. I bought a new 18 1/2 inch barrel not too long ago and I've only shot with that barrel once. I was in a gun shop near where I live the other day and saw that they had another 88 for sale, great condition, and was the 8 shot security version. I'm wanting to see about trading my 88 and the new barrel to get this version. I believe the price tag was $232.99. I bought my shotgun for 220 and the new barrel was about 90 bucks. I am not an expert haggler so my bartering skills are close to none but I was hoping someone could give me some advice as to how much I should get off the newer 88 with my trade-ins so I know what is a good deal and what is me being swindled Anyways, I would really appreciate any help I can get. Like I said, the 18 inch barrel is practically new, and my 88 is in good shape but does have a few appearance scratches and wear but its completely functional. Thanks again!
