I think you'll be able to at least get rid of them without taking any sort of loss. You have to take into account the "good" PS3 cost $600 at launch in comparison to $350 for the Deluxe Wii U. When people start seeing $1000 or more which was the asking range during the PS3 launch they get scared...
Marlborough started 50% on Wednesday, someone took the only 360 on clearance before I got there sadly. I went Tuesday night and it scanned $289 unfortunately, that's the luck of deal hunting.
