These Backyard BBQ Kettle Chips were a great deal with the promo code.  It was nice to have a larger size bag.  Some Kettle Chips in the grocery store are only about 5 ounces and we polish them off in one family lunch!  They arrived fresh and were not in crumbles as some other chips from Amazon Grocery have been.  Great flavor and All Natural!

Switch tastes more like chemicals than juice. I was expecting something along the lines of Orangina, instead it's closer to orange soda but without the carbonation level that makes orange soda enjoyable. For a small drink (8.3 oz), it's pretty high in calories (140). Frankly, I don't think the flavor is good enough to justify the caloric level.  Bottom line: If you're die-hard soda drinker, this might be a better option for you. If you're a die-hard juice drinker, stick to juice. If you want fizzy juice, add a little seltzer to your fruit juice.

These little cups are a waste of money. The Kerug machine had a difficult time processing the coffee through the cup, and as a result I ended up with several half cups of coffee.  I tried it about 10 times, and then gave up.
