If there is one thing I've learned by now it's that Amazon.com bestseller list # means squat.
I'm not even 100% sure it's accurate within Amazon (sometimes it lists things on top that are just way out there, almost as if it's more advertising than truth). It also manages to list items on top that are out of stock and hence, are not sold*.
*) Though that could mean people ordered it at that time even though stock had run out. Which doesn't make the list more accurate though because in that scenario actual sales (i.e. when the card gets charged and the product shipped to the consumer) are not based on that chart but on the manufacturers shipping speed of new product.
