I have a 2lb bag of Nativa brand Yerba Mate. I will not be drinking it, and I got it for free for an article. So if you're interested, give me a little PM and I'll gladly send it to you, no tea needed in exchange. I may also have some mate teabags I'll throw in too. Hopefully I can find this bag, but I'm pretty sure it's in a box in my living room.

It's the first item on the list.
