Deal Applies for both Grey and Green.
Not the cheapest this has been, but typical sales are ~$550 and the all time low is $506.59 with the Afterpay Deal(s).
Decent deal if you already have ebay plus, otherwise you may like to wait for a better price as we're at that time of year.
It may also be possible to get this cheaper via education store + trade in of a cheap device + the newsletter sign up but YMMV on that.
Good deal
