$20 seems steep for a single book to ship, why are there no shipping options available (especially when it's just your normal site), it feels a bit shady to claim the book is $24, and then charge $20 shipping on your own 'pledge-manager' like... backer kit already is a pledge manager... Especially when you list the book for $40 afterward, it seems like you had a false cost listed and are making it up in shipping. I just paid it, but unlikely to continue supporting you. I couldn't find a contact option easily so I put the complaint here.
