Out them
I wish I could prove it man, oh how I wish I could..........I would love to drive the bus that I throw them under.....
Then how do you "know" they do this?
When you see something that doesn't add up, like an auction with only a few bids, that is 10x or 20x higher than any BIN, and the BIN are in a better grade for less, .....C'Mon man. I cannot hack the accounts to confirm, but if it looks like poop, smells like poop. Likely poop. And really easy to "set the market" mark the item as paid and shipped, pay a few fees to then sell others for "market". It is impossible to stop 100%.....
The same thing happened a few months ago with the Sorrentino variant for Deathstroke 1. A few copies sold for well over $50 when the book was still available at Midtown and others. I quickly bought 3 which was the max allowed at Midtown for $18 each. I reacted without giving it much thought and then buyers remorse set in when looking at the closed auctions and seri ting it was a few bidders and some were won higher than BIN prices. It didn't make sense. When I got the books a week later I quickly sold them and more than doubled my money. I believe the book has continued to sell strong. I don't know if the market was manipulated or not but it worked out. I picked up 2 of these at cover, if I miss I am still playing with house money.
