Not sure about the in-store price of the Xbox One, but base price PS4 in store was $329.99, with this flyer (applicable 11/27-11/29):
$329.99 - $50 = $279.99
The PS4 in the store did not come with any games and I was not sure what model of PS4 it was. The only PS4 that shows up online is the Uncharted Bundle with Black Ops and a charging cradle for $399. But if you are like me and have already played through all of the Uncharted games, a trip to your local costco for a $280 PS4 may be worth it.
