Tom J. pretty well summed up a whole lot of words on the FTC site (unfair
practices, etc.) which I searched about 6 months ago. In short, if you
never advertised and sold a product at a higher price, then you cannot
advertise it at a sale price - legally.

I also shop at WW and have a friend that works there. Pricing is done by
corporate and to say they're a bit confused at times is being kind. In your
situation, just ask them to do a price match (they will) and the store will
call corporate who will confirm the price at the competitions store and if
it's a valid apples to apples deal (not a close-out, refurb's or other
discontinuing line type of sale price) they'll match it.

So don't blame the poor guy at the store...he has absolutely no control over
the pricing and suffers with every mistake made a whole lot more than you.
Doesn't make it right but hey, stuff happens.
