Ex Input:
I have been searching for a natural lemonade drink mix that would actually taste good.  This is not one of them.  Did not like the the bitter taste of this drink mix. I can make my own fresh squeezed lemonade better than this stuff.  In the mean time I purchase Newmans Own ready made lemonade if I don't have the time to make my own lemonade.

Ex Output:

I have this on auto ship because I use it so much. I have gone to every grocery in AZ and the cheapest place is Amazon! This is a great product and whatever you make using this flour will taste great. My son has Celiac and is allergic to gluten. I have tried every pancake mix and this one is the one I settled for!

My 50lb bag of oatmeal seemed like way too much, but as time went on I found more and more uses for it. I have so many recipes that I make weekly that I'm running out! This is a very high quality oatmeal and much cheaper and better than anything I've found in the grocery store.
