Found these while looking for good, cheap, low-calorie snack packs to buy in bulk for my office. After my first shipment, I decided to have two boxes shipped to the office monthly via subscribe & save. My next shipment arrives in two days. I'm so excited! Gotta have my pop chips...

I got this for Father's day and my dad loved it and did not mention one thing about it being small or anything. This really made his day so I am pleased with the idea to order the gift for him. I would recommend it!
