The receipt doesn't make it clear exactly what it relates to, many of the Target employees don't know about the deal so you may have to ask them to scan the two items together to get it at $66.51 (or quote them the item codes as shown on the receipt). I think it's for Xbox 360 only?
The headset model is Ear Force XLa. RRP $39.95, link below:

Edit: I think the same deal is available for PS3 but different headset:

Got the PS3 info from here:

A bit more info would be great, what model are the Turtle Beach?
