LOL, about the bubblemailers, I'll start collecting them at work. Once I have some, I'll send them to someone in a box. (or, I can send them individually for the cost of shipping, but that's less useful)
I can only get about 1-5 daily, As it depends on what arrives.
They use them for small plastic parts (Mainly for Fujitsu tablets), and often they come unsealed in a box. If they don't want the part back (which is common for the smaller parts) then we normally throw away the thing.
I can also get tons and tons of cheap bubblewrap, but it's really more useful for larger items.
