What's up with these 'ebay' emails

that have the subject line with:
RE: Question for seller -- Item #379741125
and the text of the message says something like:
Hi, please add another $19 for shipping to Alaska.

Hello, what is the shipping cost to Saskatchewan?
I'm getting 1 or 2 each day, and I know that they're bogus. However, I don't understand the point. I cannot figure out how someone could be scamming money off this, or what the intent is all about.
Anyone know?
