If you previously were on the Advanced Plan and downgraded to the Basic plan then price add-ons will still show on your products but they won’t work correctly when a customer goes to checkout.
You can remove the price add-ons with the code below.
Add this code to the theme.liquid file after our app’s two lines of code. Here is more info on editing theme code.
<script> var bcpoDisablePriceAddons = true; </script>
