The prices in the big stores (Gander, Bass Pro) around here are so insanely high I never even attempt to buy there, but I highly doubt they would haggle. Too many dummies in there that will pay retail or over. Most of the local guys will haggle a bit on the used stuff, even if it's just a few bucks. New guns are generally priced at their minimum.
I consider those who cause innocent people to be defenseless through advocating and enacting "gun control measures" to be murderers by proxy.
