I used to supply my mate addiction at the Shop&Bag on Walnut at 43rd, which had a whole range of brands and types (with stems, with powder, just leaves, etc) -- kilo sacks of loose leaves for $11. They still have a decent Latin American section but they stopped carrying mate altogether.
Whole Foods carries little bags of the expensive organic Guayaki loose-leaf mate, but that's a little fancy for my habit. I've been randomly poking my nose into bodega-type places, to no avail as yet.
My stash is running low! Does anyone know where to get reasonably priced bulk yerba mate in Philly?
Thanks, you guys!
