We'll start shipping Bianca worldwide very soon (hopefully before the end of next week if things go as planned). The price is a little more than $14
It's $30. It's all inclusive (shipping, taxes included). The CD is nicely printed and inserted in a beautifully designed DVD case, with a copy of The Linux Mint Tips And Tricks (a 12 pages booklet of tips and tricks about Mint, mintDisk, mintMenu...etc).
Alternatively you can order Mint CDs for only a few bucks from other sources and make a separate donation of the amount of your choice from the linuxmint.com page.
PS: Thanks for the feedback and suggestions.
