I've earned points/VIP tier with my last purchase, but now I want to return it. What will happen to my reward?

If you use your rewards towards a purchase and later decide to return that item, your rewards will be credited back to your rewards account. For example, if you use $10 coupon towards a $100 purchase that you decide to return, the $90 balance will be refunded on your credit card and the $10 reward credit will be deposited back into your rewards account.
