TonK, if you want to ban all the people who have sold things here for more than they paid for them, you'll be banning almost every member of the site, including yourself.
Selling something for more money doesn't make him a KPJ jr. To be a kpj jr, he would have to include deceptive description and photos, to try to make you think he was offerring extra stuff that wasn't actually included with the item.
Anyhow, I've had 3 (or 4?) great transactions with Datalogic, and have no complaints. It's been pointed out to me that I probably paid $5 more than I needed to for an AOF2 mini marquee, but so what? I knew that, and I didn't want to wait to find another one. I'll live. Otherwise, if something is overpriced, I just won't buy it. Simple.
