Welcome to PriceMux

PriceMux is a Shopify app that solves a specific problem: you want your online prices to include shipping, but you also sell in-person and your in-store customers shouldn’t pay for shipping they’re not getting.

How it works

PriceMux gives you a rules engine to express “what should the online price be for this variant?” — typically as a function of its weight, vendor, tag, or collection. The rules apply automatically. Your Shopify-stored base prices stay clean, and PriceMux maintains the online prices as a derived layer on top.

At the point of sale, the wedge inverts: the POS extension reads the variant’s base price and subtracts the shipping component, so the in-store transaction matches what you’d have charged without shipping baked in.

Who it’s for

• Shopify retailers selling physical goods both online and in-person
• Stores on Shopify Basic and up — no Markets or B2B catalog required
• Operators who want pricing changes to be auditable and reversible
