1 Limited use: The Angel Card can only be used in Victoriaâs Secret and PINK stores. 2  While you may also use the card at Bath & Body Works stores, you will not earn Angel Reward points on those purchases.

These sales are huge (some ladies ransack the displays to find the best deals) and they get tons of people into their store.
