The quantity sold of the JFK set actually went DOWN by 259 sets last
week ... clearly the number of cancellations/returns exceed the number
of new purchases. Will The Trend Continue? How Low Can They Go?? Tune
in next week, same Battime, same Batchannel!!!

Where do you find these numbers on the Mint site?

At the bottom of the website page should be a site listing, under, About, is a "Production & Sales" link. It is updated weekly.
