SAMSUNG 750 EVO 120gb

I purchased this drive last week and installed it in a customers laptop. Now he brings me another and wants the same drive in it. The Amazon I used is out of quantities. Only ones I found on ebay are overseas. Newegg search shows none.
Was this drive discontinued? I cant seem to find it.

The 750 EVO were limited release in Japan, just use the 850 EVO, it's better anyway.

Now I notice the Jap text on the back. It was shipped from USA. The 850 arrived today.
