ebay is sincerely managed with a non American communist ethical base.
You can buy and sell houses and pornography on ebay, but not butterfly knives, automatic knives, or a variety of gun related parts.
ebay fees have gone from about 1% to 10% over the last 15 years. Higher overhead than a retailer with a string of buildings.
gunbroker fees have gone from 1% to 3% over the last 15 years, guns, autos, and butterfly knives welcome there.
If you wish to honor ebay based on personal ethical conviction that is very respectable. I have no desire to argue about the ethic or motive of such...but I sincerely feel ebay is an anti American communist sort of entity.
I am addicted to trading blades, so I use them...and I do mean use them. Pay a lot of fees, but avoid what I can--not out of selfish monetary addiction--but to beat their BS communist rules as a sort of combative victory hoorah, help legit men in other places enjoy an over governed blade, and fund my addiction.
I am surprised by how much condemnation is shared here re this subject, but I here you and see some legitimacy in it, and it makes me consider my orneriness.
