Vincent Paul Two White Guys Tried to sell me a Vincent Paul Home Theater System ,Scam, Chesterfield Virginia

I was approached yesterday around 5:30 pm after leaving out of the Sheetz on Midlothian by two white guys in Silver Van with North Craolina tags selling a Vincent Paul Home Theater System valued at about $3700 but ws only asking $800. I was kinda curious at the time about what brand the system was because I was in the market for a system for the house,so I said let me see what you got. Now I have never seen these guys before or know where they're from, so I'm a  little cautious. The driver got out shook my hand introduced himself and gave me a lame but classic spill about how the system was for a customer that he was supposed to install,but the customer back out at the last minute leaving him stuck with the equipment,so he was willing to take $800 just to get rid of it. Now I'm a little more street savvy than the average guy and smelt Street Hustle from the jump. I notice they had no tools at all. I guess you know what I'm thinking about now. So I googled the name brand because I've never heard of the brand before. Immediately a Scam report popped up and  pretty much describing these guys and the tactics being used and one of  the victims finding rocks in the speakers to give them weight. I declined the offer then Immediately the guy  then asked me what will I be willing to give him ,I said I don't know. To make a long story short the price went from $800 to $360 to $250. I wanted so bad to tell him that I'm a  Business Relations Representative with the Better Business Bureau and I appreciate the offer but no thanks. Wow!
