Flip job!
INow I run my own archery shop and sign business, when I buy a used bow off somebody, put a new string and cable on it, freshen it up some and ask $200 more for than I paid for it after I took the time to buy it, freshen it up and try to make a profit so I can eat tonight Im breaking every moral and ethics code in the book?
No one ever said anything like that. Or even close actually. Someone has a pretty good idea a shop owner is looking to flip something when they go to a shop to sell it.
Now, if you represented yourself as a guy barely getting by who could really use a sweet deal on a bow, or really needed something to feed his starving family (could you come down a couple of bucks?), then yes, that would be immoral.
I'm not saying someone should have to declare their intent to flip, but they needn't make up any BS stories either.
If you buy something from someone for $2500 and you know its worth $25,000 (as is), yes that is immoral. I am not sure where the line is between getting a good deal and taking advantage of someone, but its somewhere before 1000% profit on a multi-thousand dollar item.
"Morality is the enemy of capitalism. Fortunately, it is easily exploited for financial gain."
Also: I find when I buy a part or something, then change my mind about it, I have to ask a higher price, just to stay even. There are a lot of guys out there who think they have to knock some off of asking price or they won't buy. If you want to be sure you get a ton of lowballers, just put "selling for what I paid for it" in the ad.
