Check bodybuilding.com, they run deals sometimes. Edit: link added.

Yeah, its still a pretty good deal. 3.5 pounds of primo protein for 11 bucks?

The same amount of the same protein is 56 dollars on Amazon http://www.amazon.com/Optimum-Nutrition-Platinum-Velocity-Vanilla/dp/B002QZORGK/ref=pd_sim_hpc_6
