Sorry - Googled it ....
Taken from Amazon :- The Raspberry Pi is a groundbreaking new microcomputer platform that currently sells from between $35 and $40. Any price over that is price gouging and you'd be unwise to purchase from such a seller. Do yourself a favor and do a direct internet search for Raspberry Pi and price to make sure that you are getting the best deal. I am hopeful that those prices will be on Amazon.
The Raspberry Pi is a fantastic platform on which kids (or anyone) can learn to program and work with their very own computer. My own kids are using one as an interface for all sorts of science experiments learning to code with the Python programming language and using another Raspberry Pi as a media center. I also visit my local hackerspace and see what other people are doing with the Raspberry Pi. You should seek out a hackerspace in your area for assistance!
Purchasing a single unit such as listed above will not give you all that you need to operate the system. You will need an HDMI monitor (or DVI monitor with an HDMI to DVI converter cable), a power supply, USB hub, USB mouse, and USB keyboard for a minimal set up. Good luck!
