(check around, no one sells it at retail price and you won't find it going for over $500 anywhere)
Heck, even a 20 pc set of Henckels Professional Series goes for $599.99 on sale:
Remember the 18 pc Cutco Homemaker +8 set is now selling at $840!
It's pretty obvious Vector looked around and came to the simple conclusion that Henckels is cheaper, so they went with an ad for a set that has 5 more pieces (that's 27% more pieces) than their Homemaker +8. A better comparison to the Henckels 23 pc set is the Cutco Ultimate set, but that's $1600
You didn't expect Vector to actually not mislead their customers or recruits, did you?
