Ex Input:
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...

Ex Input:
It's high-quality and the price is right, especially with subscribe-and-save via Prime, but after months of trying to keep up with my subscription, I had to put it on hold. I'm not a big water drinker, but this stuff has a distinct flavor and when you're using it as a work-out beverage four or five times a weak it eventually wears on you. Or me, at least. I'd still recommend it, just don't OD the way I did.
