You're paying way too much.
This site sells turmeric for $2.95 per pound. Google "turmeric" or "shop turmeric" and you can find a lot of other sources too. I bought very nice quality bulk turmeric from India at an Asian market in Albuquerque. That was Laxmi brand and was $2.50 for 14 oz.'s. The website above sells Gel-Caps and a
machine to fill them easily if you have to have capsules.
