Two books for beer lovers (whether it's for drinking or cooking) are on sale for $2.99 from Storey Books. If you buy them from eBooks.com, you get both the epub and PDF versions (and the PDFs are very nice, coffee-table-style books with many illustrations). Kobo only has the epubs, but they're couponable if $2.99 is too steep.
