Ex Input:
This bone is nothing more than a big dog treat.  I have a 2 yr old Pit who ate through the souper in 5 minutes.  After reading other reviews I took it away from him and will save the rest for a later date.  I was hoping for a bone that would last a little bit longer as a chew toy and not just be eaten like a treat.  Will not be buying this again.

We bought these chips at a little sandwich shop in Sonoma while we were on vacation. I wasn't sure what to expect by the package, and at first bite I didn't know what to think...and then all of the flavors hit! Yum! They are a bit spicy, but nothing overpowering. Just lots of crunchy, sweet, spicy goodness. They aren't sold everywhere though, I'm still trying to find them somewhere close to where I live.

... get this type of sugar any other way than through ordering it because the shipping is INSANE!  The sugar is fine but for the price of the shipping, it was not worth it.
