I ordered these because I had purchased a bag of Sweet maui Onion chips from the supermarket. They were so good that I had to get another.  The order came and I popped open a bag. They are very crunchy, so if you're into that, these are the chips for you. However, they do tend to get really salty. I found myself having quite a few sips of beer when eating these

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!

Having recently been placed on a gluten free regime, I felt I needed some quick and easy help to get me started. It works great but is way too expensive for what it is. There were just over three cups of bisquick in the box. When I read the ingredients, I realized I could quickly mix up my own quick bread flour and keep it in the fridge. I'm glad I tried this item because it taught me that I could do just as well on my own and save a great deal of money.
