Cashback terms and exclusions

What will stop me getting my cashback?
  • Using a discount code or voucher code not posted and approved by TopCashback.
  • If you return or cancel your order then you will no longer be eligible for cashback and you will see the cashback move to Declined in your account.
What else is essential?
  • Most retailers calculate the cashback based on the purchase amount excluding taxes and delivery charges. So if your cashback is slightly lower than expected, this will likely be why.
What to do and when
  • Any Missing Cashback Claims must be lodged within 100 days of your purchase.
