I call a brick and mortar store looking to buy a listed used firearm. I would have LIKELY bought at the advertised price- but it never hurts to ask right ?
I asked if they would consider an offer of 94% of the asking price, and the reply was, "This gun is on consignment with a dozen others and we only batch process price reductions, these were reduced 2 months ago and aren't due for another reduction yet."
I reply, "So you won't take this offer to the consignor? "
"No, you can keep watching the site for another reduction"

I am wrapping up a different purchase at another store on the phone as we speak.
