Yes, this is possible today. Chamevo has a built-in Print Locations pricing rule that charges by how many sides a customer prints on (front, back, sleeve…). Setup: 1. In WordPress, go to Chamevo → Pricing Rules and click New pricing group. 2. Give it a name (e.g. "Per-side surcharge"). 3. Under What does it price?, choose Print Locations. 4. Set Match type to All (summed) — this stacks each threshold so every extra side adds its own charge. 5. Click Create group, then add your thresholds. For a base price on 1 side and +$6 per additional side: | When (print areas) | → add | |--------------------|-------| | ≥ 2 | $6.00 | | ≥ 3 | $6.00 | 6. Assign the group to your product(s). Result: - 1 side printed → base WooCommerce price only. - 2 sides → +$6. - 3 sides → +$12. It counts only print areas the customer actually places a design on (empty areas don't count), and it's calculated once per item — so no double-charging. For the bulk/quantity discounts you mentioned (50 shirts at a lower per-unit price), that's handled by WooCommerce's own discount/bulk-pricing tools rather than Chamevo's rules — happy to point you to a setup for that.
