I bought these at walmart for less then $2.00 dollars a box.There over  $2.80 a box @Amazon for (box of six).Then you need to add another $7.00 dollars to your order to get free shipping ....I would not buy these again could be better if you added chicken or an egg like other reviewers mentioned. My box does say gluten free so maybe there are 2 versions.

My son and daughter-in-law told me about these chips and they purchased a few bags at a store and I will say they are higher in stores then you can get them online on Amazon. They brought me a bag and I was hooked! So I ordered popchips online and they are the "BEST" chips!! There wasn't a flavor I didn't like or that my family didn't like. I am a (chipaholic) and these are better for you and a great tasting chip. I highly recommend these to anyone that can't do without eating chips either with a sandwich, hamburger, or just to munch on midday. You won't be dissapointed.

I like the DisposaKups.  If I'm fixing more than one cup, it's quicker to use the DisposaKups than it is to clean out the refillable holder, which came with my machine.
