This is Vince Offer with the Slap Chop which you've probably seen. Notice that he says it's $19.95 and you get a Graty and a second set free. The S&H is doubled for the second "free" set, so it's really $19.95 + (2 x $7.95) or about $36. They ask you to ask about the foldable cutting board (Basically a 10 cent item) which is only part of the Platinum Set. But if you get the platinum set which they'll try to upgrade you to, then it's an additional ($9.95 + $3.95 S&H) x 2 for a total of about $64.
He's so slick that he's kinda fascinating in a sick sort of way. Yet his speech and mannerisms scream that he's a scam artist.
Would you believe Vince is not his real name? Hard to believe since he seems so honest. ;)
I won't post the link to the site that sells the SlapChop to protect you. It's a really obnoxious site. Before you can quit it, it asks you if you're sure. Then it has a dialogue box where Cancel keeps you on the page and OK lets you quit it. It will let you save $5 on the set when the special internet offer pops up ;)
Needless to say, I don't recommend his products.
