It depends on which version of the Pipeline theme you’re working with. Make sure in the backend of Shopify on your product page you have a ‘compare at price’ listed and then you can go into the Theme Editor and make a few adjustments. See attachment.
Sounds like you’re using an older version of the theme. I’d recommend
emailing the theme developers and asking. They usually reply within a day
or two.
Try looking in the theme settings under ‘Product card’ & ‘Product form’ sections. The placement of this price setting seems to be different depending on which version of the theme you’re using. If you still can’t find it just email the developers.
