Example Input: Great price for an excellent chip. At about 80 cents for a 2 ounce bag these are a bargain as well as a very tasty chip. Everyone I've let try these has been impressed and commented on how good they taste. I've yet to find a Kettle chip that disappointed!
Example Output: 5

Example Input: This stuff is pretty solid. Makes a decent enough pancake for being GF and makes a solid biscuit as well. What we have found works best is taking this mix and using it half and half with the Chebe mix. Between the two it makes for a very nice flour mix. The Chebe is good but on its own tends to be a little squishy, but when you mix it with the bisquick, the bit of squishiness gives the dryer Bisquick the fluffiness and moistness it needs. So, I recommend this, but I would HIGHLY recommend getting some Chebe too and cutting the Bisquick with it. Also, even though this mix has leavening agents in it, when we use recipes that call for leavening agents we add them anyway, it tends to turn out better this way.
Example Output: 4

Example Input: I ordered this because so many people were saying that it was sugar free. It's not. The first ingredient is "SUGAR". It's too much of a pain to return, so I'll keep it and drink it (because it's a pretty good K-cup hot chocolate). I will think twice about ordering it again though. I'd really like to get what I ordered.
