I think this should be stopped. I have a ton of water bottles, mugs, shirts, USB chargers, pens and other stuff I will never use and often just throw away. Not only do I not need the items but usually they are just cheap crap that breaks if you actually use it. One company handed out Patagonia shirts which actually were good quality but most companies are too cheap for that.

Just stop. It's wasteful and harmful for the environment. If they want to make me happy, give me some cash :-).
