Online-
- Amigofoods.com - has a good selection of many Hispanic food items, as well as yerba, but can be quite pricey. I have ordered from them and found them to be quite fast
- ma-tea.com - not a huge selection of yerba but much more reasonable price for the selection they do have. I have also ordered from here and found them to deliver on the faster side.
- mymateworld.com - a decent selection but also pricey- their website is very confusing.
- "Homemade" yerba from sites such as circleofdrink.com, republicoftea.com, theteaspot.com are some choices that sell their own yerba. I have never purchased from any of these but could be worth a try.

- Whole Foods - carries Guayaki and Eco Teas. If I am in a pinch, then I will go and get Eco Teas as a substitute.
- Local Hispanic Markets - have had decent luck finding Cruz de Malta sometimes and at very cheap prices
- If you are in Chicago - Buenos Aires Deli has a great selection of all things Argentina!
I do not endorse nor am associated with any of these companies or shopping sites, this is just meant to help guide you in the right direction if you are looking for yerba online.
