Calculator
What free membership saves on the OPMS you already buy.
Choose your usual OPMS format and reorder cadence. The calculator compares our published guest price with the product-specific member price—without pretending every item receives the same discount.

The math uses the same OPMS product and quantity on both sides. Only guest versus member pricing changes.
The honest limitation
Prices and availability can change. Live checkout must use the current BigCommerce/Lightspeed record; this tool never invents a competitor price or an extra percentage discount.

Fine print, said out loud
What this calculator does and doesn't do.
- It uses the selected product, current guest price, current member price, quantity and cadence. That's all.
- It compares the exact same OPMS product on both sides; it does not compare effects or products.
- Member savings are product-specific and are not a blanket percentage.
- Shipping is excluded on both sides. Free over $75 either way.
- Bulk checkout remains unavailable until dedicated 10-pack and case SKUs are live in BigCommerce/Lightspeed.
