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!

I used this mix to make a 9x13 cake in a glass pan using grapeseed oil, spring water, and free range eggs.  I thought the cake had a nice flavor to it but it was not what I was expecting.  I was craving a white cake (like wedding cake) and went to my local store to find something wheat-free, gluten-free and dairy-free; I purchased this vanilla cake mix.  I think it is a very good mix.  I couldn't really taste the vanilla flavor but thought it had a nice flavor.  The cake is yellow, dense (but not like a pound cake) and texture-y like brown rice has more texture than white rice.  I thought the sweetness was just right.  I think I would purchase again but would make pineapple upside down cake with it.

I first had this popcorn at my 84 year old cousin's home. I thought it was so tender and delicious, and I wanted to buy some for myself. I found it on Amazon.com believe it or not!!!  Anyway, I ordered 6 pounds of it. All 6 pounds are now gone. This popcorn is REALLY good. It is different than other popcorns I have eaten because the kernels are small and very delicate. I consider myself a pro when it comes to popcorn because I have eaten it every night since I was a little girl. I usually eat my popcorn 1 kernel at a time, but since the kernels are so small, I ate it by the handful. My only complaint is that it does cost a lot to have it shipped. I wish I could find it locally so I would not have to pay for the shipping costs. If you like popcorn, I highly recommend it.
