Plastic-free courier packages

Hooray, I've been able to update the Plastic-free actions post.

I use couriers a lot at work, and recently I've discovered that you don't need to use the plastic TrakPacks, you can just use a regular (paper!) envelope and stick a courier sticker on. Since I courier stuff at least a couple of times a week, this represents quite a saving on plastic.

I guess if you're a dyed-in-the-wool greenie this would seem obvious, but I had always assumed you need to use the official plastic bags.

Now I know there's another option it seems obvious to me too.
