Ex Input:
I've used this BBQ sauce before and it is good especially considering that is free of so many negatives (like corn syrup and for us gluten) but the price on this can't be right.  Order directly from the Daddy Sam's website to pay $5.50/19 oz bottle.  This price would HAVE to be a case price although the description says 19oz.

We didn't care for this product at all. It seemed to have a funny after taste to it. Wasn't worth the cost. We were unable to even finish using what we purchased it was that nasty.
