I bought 2 copies for $2.99. A friend in .ca told me he sees $31.99. I went there to gift him one. It was $4.99 by then. Gifted it anyway because it's was the best deal I ever had (It's worth the original price but it's a bit too far for me).

I have a Kindle connected to my account (My friend didn't) and I have a US address listed (I'm Sri Lankan).
