Delicious candy but expensive

I love SmartSweets! I’ve tried the peaches, sour gummy bears and original gummy bears. I love that I can eat them while doing low carb. They actually do taste like the real thing. I’m trying to eat low carb so I wish they had a lower sugar content. Sometimes I go on Keto and I don’t know if eating these candies would kick me out of ketosis. They are also really expensive so I’ve only bought them a handful of times. I wish they were more affordable so I could buy more. Also, they keep promoting no sugar alcohols. I’m not sure why as I eat sugar alcohols when I’m on keto.
