Clearance one:

There is also this one which seems to be newer version @$128. It is much more available. The box is sealed in hard plastic compared to the other one which is just in the box. It has 2 different barcodes on the box. It has a new barcode on the back, but there is also the old barcode on the side that rings up at the clearance price, so YMMV on getting the cashier to ring up the clearance barcode on the side instead of the new one on the back. I had purchased a clearance one and the associate agreed with me that they were the same thing and rang up the second barcode for me, but definitely YMMV on that, but is worth a try
