My first, unplanned, foray into vehicle/minifig part-outs: After buying a 75102 Poe's X-Wing from Amazon for $76 shipped, found a better offer a week later from KMart for $63 shipped. Contemplated returning the one from Amazon, but (cheap as I am) didn't want to pay the $7 return shipping. So I split out the 4 minifigs and put them on BrickLink & BrickOwl, and listed the X-Wing as no-box, no-minifigs on EBay during the 40% off sellers' fees promo.
Sold all of them within 2 weeks, making $90 after shipping and fees. And since I claimed tax back from Amazon making the original purchase $71, I basically got a 75102 X-Wing for $44 all in. Can still lower that a bit more if I decide to list the box .....
