Given the task definition and input, reply with output. You are given a review of Amazon's food products. Your task is to divide them into two classes: negative or positive, depending on the content of the review.

I wish I found the plastic refill packs instead of 6 giant metaL cans - seems like a lot of wasted packaging. I just didn't know to look for them until much later. But, its much cheaper from amazon than the gocery store. Probably about the same price as costco but no tax here and super convenient. And, the formula mixes well, my kid loves it and (most importantly) his poops seem normal...not nasty formula poops if you know what I mean!
Positive
