The terms and condition state to allow 2 to 4 weeks after an eligible purchase is charged for the credit to hit your account. However, in reality a lot of times this credit may hit within 2 to 5 business days. If your credit does not post to your account within four weeks then you should call the number on the back of your card to inquire about the credit (online purchases may take a little bit longer to process than in-store purchases).
