customize checkout

Topic summary

Issue: Changing checkout page text did not apply after editing the default theme content. The user is seeking a way to modify the checkout text specifically, indicating that theme content edits didn’t affect the checkout.

Request: Remove the existing “sale” line on the checkout and replace it with a custom tax line that displays: “כולל ₪40 תשלום מע"מ” where the 40 is calculated dynamically as price × 0.17 (representing 17% VAT of the purchase price).

Details: The desired display is a Hebrew text indicating VAT included, with the amount computed from the order price. A screenshot is attached (image) presumably showing the checkout area to be changed.

Status: No solution or steps provided yet; the user is asking how to implement these checkout changes. Discussion remains open.
