You can enable Staples Reward card benefits by signing into Staples.com using your rewards card number. As of 2015, it is not necessary to activate the Staples Reward card, but an online account linked to the card number is required to accrue rewards.
Members of the Rewards program can earn up to 5 percent cash back on purchases made both online and in-store. Other benefits include free shipping for online purchases, $2 back on ink and toner recycling, and free copy and print services. Rewards are sent via email or regular mail depending on the customer's preference. Check reward status by logging into Staples.com.
