I was on subscribe and save for these mints, but have switched to Spry due to Xylitol USA's awful company policy and customer service. If you buy something from Xylitol USA that arrives in bad shape and you want to return it for a refund, the company will tell you that they do not accept food back. When I insisted that the product was old (in my case two bags of xylitol sweetened dark chocolates that were old, whitish and tasteless) they said that they would NOT refund my money and, amazingly enough, offered a 25% discount on my NEXT purchase. I disputed the payment and my bank took care of the situation got me my money back. No more purchases from this company for me.

While the product is delicious, it's annoying that the peanut butter stays on the waxy paper instead of on the product. You need a fork to scrape the peanut butter off the protective top sheet.

This is the second purchase of Kettle Potato Chips and we love them just as much as the first time we tried them. We bought them by the a carton of 24 bags. The Kettle chips were in a 2oz bag which is just enough for a single size serving snack or with a meal. The chips are so delicious, baked not fried and lightly salted with Sea Salt. They have 0 fat, no preservatives, nothing artificial and they only use real food ingredients. What more could you ask for in a great tasting chip!
