Mobile First Interactive Pricing Component Using Vanilla JS/CSS

Hi, just completed this challenge let me know what you think, i think it hits pretty close to the mark, would love to hear a better way to make the JS part of the code, i feel like a repeated myself a little too much (against the DRY rule what a sacrilege) i'm sure somebody will tell me a better way but it does the job, changes the price for every plan it applies the discount if clicked, anyway have a good day.
