you only use a tiny amound, like a pinch for a bowl of oatmeal or stevia or a tablespoon for a gallon of lemonade. It will last a long time for me. The big bags like Walmart brand, which I, personally hate, have filler and measure like sugar. I don't mind the Truvia brand. I also like the Now brand Better Stevia liquid because it doesn't have that crunchy feeling after heating. I bought a small coffee/spice grinder to I put my Stevia through if I am going to cook with it and that helps too.
