There's currently a coupon to get 20% off the No Cow bar from Amazon. These are similar to quest bars, but contain no sucralose or animal protein and are fantastic for keto because they only have 4g of net carbs with 20g of protein. They're pretty great for how nutritional they are, but don't expect it to taste like a candy bar. Also softer than quest bars. Supposedly lemon meringue is the best but I haven't tried it yet, so that's one I'm ordering.
Also, for some reason, the coupon is one use per order, but I re-used the coupon 3 times so far without issues on 3 separate orders. I also wasn't charged tax for some reason. Stack with discover 5% and they come in at around 1.90/bar
They also have the chocolate chip cookie available for 1$/cookie here:
