The last few things I've bought from Amazon were all knockoffs--Hanes socks that wore out and the fabric pilled up immediately and gave me blisters, boxers, sunglasses, etc. Pretty disappointing. Now I try to avoid any Prime products fulfilled by third parties, but I'm not sure if buying directly from Amazon mitigates the risk.
