The other thing we tested out was her paying me by sending me an Amazon gift certificate, because then I could actually use the money directly to buy the book in the first place, and it wouldn't cost me anything out-of-pocket, plus there aren't any paypal fees that way. It seemed to work just fine for her!
So, if those of you who live outside the USA are interested, like a few of you mentioned, comment or email me. The cost would be the $13 of the book plus whatever it cost me to actually mail it to you; judging from DJ's test run it'd be about $28, give or take. I'll give it a few days so if a couple of people want me to do that, I can order stuff together.
And if anybody stateside is interested and missed it before, you can always Buy CB on CreateSpace or from Amazon.
