Not sure...just that they have been dropping pricing greatly in the lightning discounts. I am set to buy something here shortly...I will let you know about what that was discounted.
If you bought from Amazon within the last month, buy this one and then just return the same one. I bought mine 6 days ago, so I am just going to ship them back the one that comes from this deal. It is costing $3.99 to return, but still, I paid $149.99. So I am still saving $43.
