Among the Kindle e-book 'holiday deals' (on sale I'm supposing from here until Christmas or New Year's) are:
Flavor Flours $2.51
Roots $3.99
Heirloom Beans $2.99
Pure Dessert $2.99
Roots has been on my wishlist since it came out, and I've been waiting for it to appear at a bargain price in some form. I went ahead and sprang for Flavor Flours at the same time, since it's also on the wishlist.
That makes nine Kindle cookbooks in the year we've had the device -- all less than $4. They're increasing my Bookshelf at a pace well ahead of that for physical cookbooks, even with the Friends of the Library book sale's summer blowout from library cookbook stacks thinning.
