Yes, it is possible to earn cash back on groceries purchased with a gift card while using the iBotta app, but there are some important considerations. iBotta generally allows users to earn cash back when they redeem offers on eligible purchases, including groceries. However, the specific terms and conditions of each offer can vary. Some offers may not apply if the transaction was made using a gift card, as the source of payment can influence the eligibility for cash back. It is advisable for users to check the details of the specific offers they are interested in to see if there are any restrictions regarding the use of gift cards. Additionally, users may want to refer to the iBotta app or website for the most current information and any updates on this topic. Always ensure that you read the terms associated with each offer before making a purchase to maximize rewards.
