Ex Input:
My kids loves Chips Ahoy! and I will have them once in a while as well.  But the kids refuse to eat them from this Family Size package.  Once I tasted them, I knew why.  They have an awful medicinal taste.  Really bad.  I don't what the problem is, but if you like Chips Ahoy, you will not like these.  Go elsewhere.

Ex Output:
1


Ex Input:
I love, and use the empty containers for medicine/advil in my purse, desk, suitcase. Also line with felt to keep earrings. Perfect little size to disguise small valuables when traveling and LOVE the mints. Tiny and powerful without burning my mouth.

Ex Output:
5


Ex Input:
If you're looking at this you probably already know you like these chips. This is a great deal and I have not had any problems with them going stale. The 1oz bags are a great size for a snack and help avoid over-eating.
