BTW - I traded in my Surface 2 64GB and my Surface Pro 2 8/256 at gazelle.com and got $838 ($265 for the S2 and $573 for the SP2), best part I have 30 days to ship it to them, so I can wait till I receive my SP3 before shipping it
Glyde.com is quoting $889 for a SP2. Did you look at other sites than Gazelle?
