If you are in the US, cowboom is an excellent source for used stuff that are cheaper than Craigslist sometimes IMO. They often have $100 off coupon or deal of the day stuff. I've had good luck there so far but YMMV of course.

I bought the Surface Pro 1 128GB (brand new) in July after a Staples fire sale.
Updated it to 8.1 a few weeks later.
