I first got the variety pack to try all the different flavors, then I picked 2 and ordered them on Subscribe and Save (1 each on alternate months).  It's much cheaper than the vending machine at work and they only have chips that are bad for you.  These chips are crisp, delicious, and taste salty, mmmmmmm good! Each bag has 230 mg. of sodium. They only have 100 calories in a bag, and the amount of chips in the bag is ample for one serving, unlike other 100 calorie snacks where you get 7 almonds, or 5 crackers....  Now I can have chips every day at work for lunch, no guilt!  The Salt and Pepper variety is absolutely delicious.  The plain is great for dipping, and the barbecue is full of flavor.  The salt and vinegar is very sour, if you like that type, and the cheddar and sour cream and onion varieties are good, just not my favorites.  A very good deal on Subscribe and Save, chips delivered to your door, individually bagged and ready to take for lunch.  Convenient!  Nothing bad to say about PopChips!

Bottled like an energy drink, Switch, doesn't contain the things you'd find in other carbonated beverages. There's no sugar, no caffeine, no corn syrup, no preservatives or artificial colors.  Instead, what you get is a refreshing, all-natural, lightly carbonated tangerine-orange drink loaded with Vitamin C. Think of it as orange soda without all the things you don't want. Switch has just the right amount of carbonation to make the beverage refreshing without being filling.  It's a zippy beverage made with real tangerine, apple, and grape juices, and would make a refreshing beverage, lunch, dinner, or snack-time drink.  There was a slight aftertaste that I'm chalking up to either the can or the citrus, but it didn't get in the way of enjoying the drink.  Make the "switch" to Switch.

A dark coffee that has no bitterness and is smooth as silk. Always use quality filtered water and a clean coffee maker if you want a great brew!
