He's (hopefully) making fun of a certain seller on gunbroker.com who sets his opening bids at grossly marked up prices. When I say grossly overpriced, I found a similar posting claiming the buy now price of Blazer Brass .40 S&W for $0.70/round. I saw the exact same ammunition at Walmart for ~$0.30/round ($15 a box) when you can find it. I would check with the charity he's claiming to help first though before placing a bid, because it not hard to just say it's for charity.
