I bought a week before BF. Looking at price slash, I called Google support. "Our system does not allow price match at this time, since this is special BF deal. I will be happy to process your return and you can order another at special pricing today". I received my new one, and will return a week used one in a day or two.
Wondering how software giant's system does not allow such matching. Google's loss (in shipping, handling and reselling in secondary market), and little inconvenience for the users like me! But we could save $80. Glad that I didn't have to do lot of transfer/setup, Backup from Google account saved a good deal of effort in move.
