Ex Input:
The candy arrived with some white waxy stuff on it; almost as if it had partially melted at one point.  Tasted chalky.  Not interested in a partial refund.  Next time find a way to make sure candy is not stale.

The last bag of these I got from Amazon had a lot of hollow bisquits.  It was weird ......  they just weren't solid like they should be.  I'm going to switch to another brand of grain-free dog bisquits now as there's no sense in paying for something I'm not getting (and these are expensive!)  And if it wasn't for the good packaging I'd wonder if bugs had gotten to them..... but I don't think that's possible.

Ex Input:
This is a good instant oatmeal from the best oatmeal brand.  It uses cane sugar instead of high fructouse corn syrup, so not only does it have a better sweetness, but some doctors now say that this form of sugar is better for you.  Great on a cold morning when you don't have time to make McCann's Steel Cut Oats.  The apple cinnamon is the best but the maple and brown sugar or the regular are good too.  Plus they don't require doctoring to actually tell the three flavors apart.
