No. There is no need to directly link Rebaid to your Amazon, Walmart or other marketplace accounts. You are not required to use the same email address or mailing address or other information used on your marketplace accounts.
When you redeem an offer and submit your order number to complete your redemption, the order number is validated by the seller’s merchant account. For that reason there is no need for Rebaid to link to your marketplace account.
Please remember however that you must use your full legal name on your Rebaid account. Rebaid accounts created with partial names or nicknames may be suspended, and/ or your rebate payments may not be accepted by your bank if your full legal name is not used.
