If you sell online and in person, the shipping math fights you: online customers pay shipping, walk-in customers don't. PriceMux sets channel-aware pricing rules that include shipping in the online price by weight; a native Shopify Discount Function removes it at the register. Prices write straight to your variants - no duplicate SKUs, no theme edits, no separate price book. Add a product or change a weight and PriceMux recomputes the affected prices. Requires Shopify POS Pro at the register.

• Channel-aware pricing: Online Store and Shopify POS in one rule set
