NEW YORK ( MainStreet) -- Deal junkies now have a new way to get credit card perks. American Express launched a service Tuesday that allows cardholders to earn special offers from merchants by tweeting customized hashtags from their Twitter handle after linking their Amex card to the social network through a special Web site. The offers will be delivered automatically via a statement credit within days of making the qualifying purchase online or in-store at participating merchants.
A Twitter service introduced Tuesday is the latest in a string of efforts American Express has taken to widen its digital presence.
Cardholders can find the offers and their accompanying hashtags highlighted as "favorites" on the Amex Twitter page. The deals at onset look pretty good, so long as you can actually use the purchases you have to make to qualify for the deals. For instance, right now you can get $10 back on an online purchase of $50 or more at Century 21 if you tweet #AmexC21stores. Other participating merchants include 1-800-FLOWERS.COM, Best Buy, The Cheesecake Factory, Dell, FedEx Office, FTD, Gulf, H&M, McDonald's, Seamless.com, Sports Authority, Ticketmaster, Virgin America, Whole Foods Market and Zappos.com. Amex says it will confirm that offers have gone through via @amexsync, an automated notification handle. The handle will also notify cardholders if they are tweeting a hashtag for a deal that is no longer being offered or a person is tweeting hashtags without having a synced Amex card. Additionally, questions regarding the service can be directed to @askamex, the issuer's customer service handle. The Twitter service is the latest in a string of efforts Amex has taken to widen its digital presence. In July it launched its "Link, Like, Love" service, which allows cardholders to get customized deals by linking their card to Facebook. The issuer also said last month that it has plans to link a loyalty component to its mobile platform Serve. >To submit a news tip, email: email@example.com.
