Why Does an Ecommerce Store Show a Different Total After Refreshing the Cart?

A cart total can change after refresh if prices, tax, shipping, inventory, promotions, or currency rates are recalculated. The change may be valid but confusing if the user sees no explanation.

What to check

Compare the cart before and after refresh, product price source, promotion eligibility, address and tax context, currency rate, and inventory updates. Check whether client-side and server-side totals differ.

Recommended next step

Use the server-calculated amount as authoritative and explain material changes before order submission. Test refresh and back navigation after changing cart rules.
