Input: Consider Input: I was introduced to the Blair chips by a friend. I mostly ignore potato chips because I really don't like them. However, these I like the most among all the chips in the Blair line. They are savory and can be eaten rapidly. The hot chips are good because they are so hot, I cannot eat them fast. I am so happy I cannot get them at local stores because I would eat them all the time.

Input: Consider Input: 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!

Input: Consider Input: I LOVE Old Dutch Ketchup chips but they are no where to be found in the US and pricey on eBay.  I tried Herr's but they were dull - very ketchupy but not the tangy-vinigary ketchup bite that Old Dutch has (makes your mouth hurt  in a good way if you eat too many!).  Uncle Rays are decent - more of a kick - many "loaded" chips which I like, still, not the addictive bite I love.  So - if you love Herr's these may be too much for you.  If you love Old Dutch give these a shot.  I am still on my quest for something equal to Old Dutch!!
