[US] Newegg: PowerColor DevilBox + RX560D 4GB (896SP) - 249.99$.
Buy a Devil Box, get a RX560D (this is the 896SP version, in other words, more or less a RX460) for free. I guess they are anticipating a price crash and getting creative with clearing out inventory. Still, this is a decent price, even if you plan to just sell off the RX560 and get something better, since you should be able to get 75-100$ for the RX560D with ease even if the price reduces somewhat (75$ would be pretty much trivial).
