Example Input: We cant say enought about the Gluten Free Bisquick.. My husband and all three kids are allergic to Wheat and we are on a strick Gluten Free diet in our house.. I have tried every product out there to make pancakes, waffles, biscuits and even chicken fingers and was so pleasantly suprised that this little box does it all and does it all WONDERFUL... Pancakes are wonderful, Waffles are Great, Chicken Fingers are the best Ive made and the biscuits are delish.. Cant ask for anything better.. I only wish you could buy it ina bigger box and it was a little cheaper but we are a HUGE fan...

Example Input: I first got the variety pack to try all the different flavors, then I picked 2 and ordered them on Subscribe and Save (1 each on alternate months).  It's much cheaper than the vending machine at work and they only have chips that are bad for you.  These chips are crisp, delicious, and taste salty, mmmmmmm good! Each bag has 230 mg. of sodium. They only have 100 calories in a bag, and the amount of chips in the bag is ample for one serving, unlike other 100 calorie snacks where you get 7 almonds, or 5 crackers....  Now I can have chips every day at work for lunch, no guilt!  The Salt and Pepper variety is absolutely delicious.  The plain is great for dipping, and the barbecue is full of flavor.  The salt and vinegar is very sour, if you like that type, and the cheddar and sour cream and onion varieties are good, just not my favorites.  A very good deal on Subscribe and Save, chips delivered to your door, individually bagged and ready to take for lunch.  Convenient!  Nothing bad to say about PopChips!

Example Input: The first can that I got of this wonderful oil was packed in a poor way: an old, reused box with not enough padding.  When I complained the company was quick to respond - with an apology and a new can packed well for the mail.  I was impressed with their responsiveness.  The Merula oil itself was excellent - a great treat.
