American Express just came out with another new Staples offer: When you spend $100 or more in-store at Staples by November 9, 2014, you’ll receive a $20 statement credit. This offer is available through Twitter using hashtag #AmexStaples, though enrollment is limited.

Full terms of this promo are available here. Online purchases, catalog orders or B2B sales at StaplesAdvantage.com are not eligible. As usual with these Amex/Staples deals, however, there are no exclusions on gift cards.

Update 10/15/14: This offer is no longer available, as max enrollment was reached in under 12 hours. The Visa Checkout deal below, however, is still available.

To take advantage of this offer through Twitter:

1. You must first have an American Express card connected with Twitter (see sync.americanexpress.com/twitter for more details on how to connect your Card)
2. Tweet using the hashtag #AmexStaples
3. Receive a response message through Twitter from @AmexOffers stating that this offer has been added to your connected Card
4. Then, use your synced card to spend at least $100 at Staples in-store by November 9, 2014

If you don’t have a Twitter account and don’t want to create one, you may also be able to find this promo through the other Amex Offer channels:

• Your AmericanExpress.com account – Log into your online account and click on the “Amex Offers For You” tab.
• Use the American Express iPhone App and visit the ‘Offers For You’ tab in the ‘Membership’ section
• Through Facebook at amex.co/facebook

You can also find a full list of other publicly available Twitter / Amex Offers here.
