What exactly is Amazon gaining? It sure is great for their cash flow but 
does it really pay off to lose all the undecided folks who add more 
items to their carts just to reach $25? It only seems viable to me if 
they restrict the items so much that "eligible" = ($79/# of yearly 
purchases) * units shipped separately.
