Amy's DOES in fact have teff, and a lot of it! Almost nothing is labeled in English, but the gentleman behind the counter was very helpful and patient, and gave me some great cooking tips. Good prices, good service, great food! Will be my one-stop shop for all Ethiopian-related cooking needs.

I called to see if I could buy teff there -- the lady said "No teff!" No explanation, just "No teff!" Strange for an Ethiopian grocery, and they don't seem to be big on manners.
