Naturally, there are Flyertalkers trying to figure out how to get 10,000 miles out of this promo as cheaply as possible, building online spreadsheets, and the like.

On the whole though this is just a good offer for purchases you were going to make from these merchants anyway, rather than trying to figure out whether a 1 cent eBook purchase from Barnes & Noble will constitute a qualifying transaction…
