The only one I ever got was the Mass Effect one, it had reasonable items but nothing that wasn't available separately, hoody, backpack, plush toy, badges etc. The best part was the N7 car badge that I had on my old PC. That was also just sent with a shipping label on the actual box, pretty crap really, at
least put it in one of those shipping bags.
Edit - That pin with Randy Marsh's cancerous balls was worth the price alone
