[Q]: Go to Costco, and you can buy lower than this price per oz. Currently $32 ($3 off regular $34.99)+ tax for big size = 0.83$/oz. Besides, it is more convinient to return if you kid does not like this formula Be careful, many times some sellers over price a product, and still make the product rank in the best sellers.

[Q]: I am on a low glycemic index diet to help control my blood sugar and hormone levels. My nutritionist recommended agave nectar as a sweetener since it's GI index is in the low 30's as opposed to honey in the low 50's and sugar in the mid-50's. I've tried supermarkets, health food stores and wholesale clubs. The prices are usually around $13 for a 32oz bottle and this is $19ish for 2x46oz. It's used like honey - substitute 2/3c for every 1c sugar and reduce liquids by 1/4th. I also use it in a carrot cake recipe (equal substitution) instead of sugar where I substitute whole wheat flour instead of white flour and I don't decrease the other liquids. It's delicious and you'd never know that's it's actually good for you.

[Q]: What more can I say. Barley Edible - Crunch on Sugar. Did come on time but have a feeling that they wanted this unloaded because it didn't sell or maybe bad batch. Doesn't make you sick or anything like that but you can actually find yourself crunching on sugar like you put a sugar cube in your mouth. Kids probably don't care. Hope this helps.
