Gluten-Free Flour deal on Amazon

I saw a deal on Brown Rice flour on Mashupmom, which led me to poke around a little bit at the Gluten-Free flours on Amazon. Right now, Amazon is offering Bob's Red Mill All-Purpose Gluten-Free Baking Flour, in a handy 4-pack of 22 oz packages, for just $14.00.

If you use "subscribe and save" you'll save another 15% with free shipping, and if you use code BOBS2010 at check-out, you'll get another 15% off. That should be about $9.80, shipped. Just be sure to cancel the subscribe and save in the next few days, unless you want them to keep coming.Just go here to sign up.

I have a pantry full of gluten-free flour, so I'm probably not going to buy this. But I sure am intrigued by the blend of flours....I usually blend my own with rice, tapioca, and potato flours I buy at Caputo's. Anyone try this before who can tell me if it's good?

Thanks, Mashupmom!
