in my opinion these are heads and twos above any pickle that you normally find at your local grocery store.  a lot of nice, sweet, pickle flavor.  I probably won't buy again off of amazon because of shipping charges, but if i ever see them locally, i'll buy a bunch.

Ex Output:
Positive


Ex Input:
I really enjoy these low calorie chips.  They have a good flavor with a good crunch and are crisp.  I was wondering if when ordering a case of these chips one could order their favorites and not the whole 6 flavors?  Say just 2 flavors if desired??  Its a great product. don't stop manufacturing them.

Ex Output:

Positive
