**Can I combine SintraAi cashback with other discounts?**
Combining SintraAi cashback with discounts depends on the portal’s terms and SintraAi’s promotion rules. Review the offer details before checkout because some discounts, credits, or referral promotions may be excluded.

Log in to your cashback portal account and check the pending, tracked, or earnings section. If the purchase does not appear within the portal’s stated tracking period, submit a missing-cashback claim with the required receipt or order information.
