Hastings is again running a 30% Trade In Bonus promotion this week. The ad says it works on XBox One, XBox 360, PS4, and PS3 games.
There are several games currently advertised as having a base TIV of $40, which would mean with the promo they get $52.
There is also this coupon, that gives a $10 bonus when you trade in 3 or more games. Meaning if you traded in 3 games with a base of $40 you could wind up with about $55 a piece for them.
Also, this week Hastings is giving away any game $59.99 or less with the purchase of an XBox One System. The ad only pictures the XBox One with Kinect for $499, but it's also likely that the promo would work with the new Kinectless XBO that comes out this week.
