[Mr Blake]

Good evening (at least it is here),
I have a problem that I hope someone can help me with. I figured I'd try this forum first, as it seems a catch all for discussion.
Here's what's up:
My 4 year old son recently received a TMNT puzzle (from the new series). He put it together no problem and thoroughly enjoys looking at it (and walking on it as it is a 3' floor puzzle).
The problem came when he received a second, identical puzzle.
Normally we would just return it to the store and move on.
But no one we've tried (and we've tried every store we can think of) seems to carry it.
It is a 46 piece (NOT 48) floor puzzle that is 22"x34" and comes in a resealable bag (also, NOT the "On the Go" version either).
SKU#: 12276201 (if that helps).
I'm at a loss for finding this. The only places I've found it are ebay, and amazon (which doesn't help).
Any assistance in this matter would be greatly appreciated.
