I've literally parked outside a police station in the past with a sign saying "I buy guns for cash". The PD was paying $50-100; I spent about $500 total and ended up with several nice rifles that were inherited by people who knew didn't want them and had no idea of their value.
To be clear, while I paid much less than retail value for them I showed them price comparisons online while talking to them. Some people decided to keep them, some decided to sell to a dealer later, and some people were happy to get $50 more than the police would have given them.
The highlight of that day was an older lady that had a beautiful Mauser 98k that her husband had brought back after fighting in WW2. She said she needed the money and honestly thought the $100 gift card the police department offered was fair. We exchanged numbers and she ended up selling it to a dealer for $900.
This is the aspect of gun buybacks that really rubs me wrong. They take advantage of ignorant and desperate people by not paying the fair market value of the guns. Old widows regularly get scammed out of thousands of dollars by these cops.
Incidentally, paying fair market value for the guns is also the solution to people trying to sell 3d printed crap. Offer them the pennies a plastic recycler might offer for it.
In addition, guns have value to people for more than functionality. There's endless stories of people selling "back" their grandpa's WW2 take back piece that would be worth thousands of dollars to the right collector and would be restored and enjoyed for decades, only for a police officer to at best "lose" it in transport or more likely send it to be melted down for scrap so someone could get a $50 gift card and local police can post to Twitter about how another dangerous war relic is off the streets.
NOUN buyback (noun) the buying back of goods by the original seller. the buying back by a company of its own shares. a form of borrowing in which shares or bonds are sold with an agreement to repurchase them at a later date: "a share buy-back" synonyms: retrieve · regain · recover · get back · reclaim · repossess
That's simply "buying".
Your position in this whole sub-thread is very odd.
