Great question!

Purchases you make at Rewards21 stores are only credited if you start your shopping session at your company's cash back portal or another Rewards21 service (like the Rewards21 wizard) and click to a store via a Rewards21 link. If you do not start shopping via a Rewards21 link, we have no way of tracking that you are are a member and as much as we'd like to give you cash back, we are not able to do so.

If you click through your company Rewards21 portal and make a purchase, then surf elsewhere on the web and return to that store and make a second purchase, your second purchase will not earn a cash back reward. (You must click through a Rewards21 link every time you shop at a store site.) If you use multiple windows on your browser, the window in which you shop at the store must have come from a Rewards21 link. Also, while virtually all product purchases at the stores are eligible for cash back, there are a limited number of products that do not qualify for cash back. Please see each store for exclusion details.
