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.

I've been gluten free for 12 years now, have tried many bread mixes, and I love this one.  So does my husband, who is not gluten free.  I hope that everyone supports these Bisquick products, since big brand gluten-free bread and pasta products are so rare, and so rarely good.  It was something special for me when these came out (if you can imagine waiting a decade for this, you'll understand).  If those of us with celiac disease/gluten-intolerance keep enjoying them, maybe the price will come down (though it's not bad now) and they will offer bulk deals.  It will also wake up other manufacturers.  I would happily order a case or much larger package.  I can make my own bread, but I prefer to use a mix, and use my cooking time for main dishes.  So don't hesitate to try it, I can't imagine being disappointed by this product.  However, I do find it for less at my local grocery store.
