Show HN: I invented a caffeinated toothpaste
Yeah. This stuck out to me too. $15 dollars for a tube of toothpaste that doesn't contain flouride? What am I paying for? I'll just buy my own caffeine powder and use real toothpaste that's only $2.

What you're paying for is not having to buy and mix your own caffeine powder.
