YMMV NIB Microsoft Surface Go 8GB RAM, 128GB SSD $391 @ Ebay w/ Samsung Pay

First activate the 10% Ebay bucks promotion (YMMV on getting this)
Then click through the Samsung Pay app for 5% cashback with Ebay (again YMMV)
Then go to this listing for the 8GB Surface Go at $459.99
If those three steps work for you then the final cost should be $391
