Example Input: I love these! The price is VERY good...all the flavors are really good! The peppermint one is my favorite and I would gladly take more of that before the others. Though the others aren't lacking at all, I'm just a peppermint fan! Will be buying more when my others get low! Thanks so much!
Example Output: 5

Example Input: I ordered these after a fair bit of searching online - even ordering the smaller 1-3oz bags. I will admit, I was a bit sceptical when I ordered this since it was not cheap and had no idea how good (or bad) the cashews would be...  The order came in pretty fast - like 3 days. The cashews were fresh and whole - with like 10 broken pieces. They were in 2 5lb bags sealed with clear tape.. first I found it odd but then it turned out to be a good deal; considering the second pack stayed fresh till I opened them. The trick is to actually keep them in an air-tight box so that they stay fresh longer.  The only negative I can think of is that the price went up abt $5.00 for the 10lb since I bought them.

Example Input: I love uncle ray's potatoe chips. They have alot of spice on each chip.  They taste spicy with a tang of sweet. When I order a box, I pass them out to friends who love them. My husband, my kids and I eat a whole bag at a time.  I limit myself to ordering only twice ayear. The salt content makes me blow up, but I still love them.
