scam: "first of all you must know ..."

most recent scam email i received in response to an inquiry about something on craigslist:

The item is available and it is like in the ad.First of all you must know that 70% from this sale will go the Save The Children Foundation where I'm working.I am a volunteer at them in UK and I want to continue this transaction through a 3rd part Clickaparcel delivery...I am in England and I have talked with the people from Clickaparcel already.The item is at them ready for delivery and I paid for the taxes and fees already.I worked with them in the past and everything was fine.I posted in your area also because I want to sell it fast(we need money).If you are interested please let me know for I can tell you the details.

Thank you
