I was in the market for a PS3 controller and was hoping to get a deal on a Sony dual shock controller. Unfortunately, there were none, but i came across this deal on a decent rated PS3 controller.
I did a quick search on Slickdeals and the same controller got a few TD's last month. But last month this controller was 19.99. It is 14.99 now.
I was skeptical to get it at first, but after seeing the half-decent reviews and 50% off the original price, I pulled the trigger last Friday. The controller seemed to work well for the few hours that I played over the weekend.
So thought of sharing this deal with anyone who is looking for any PS3 controllers out there. Although there may not be a lot of us, most people have upgraded to the PS4 now.
