Yea because every product (good or bad) is a guaranteed slam dunk just by placement alone. Just ask the Spongetech fans who had their products in plenty of Fortune 500 Retailers and never sold any - lack of interest they call it.
Cabinets and Vanities are a look and value thing. If the look is not appealing I don't care where it is placed, it won't sell. as for this interchangeable gimmick (which it is), how many people change their vanity look like they change clothes? I don't go out to buy a vanity thinking - hey I could change the panels next month if I want, what a bargain.
