Its prospects for success? Not bad, Bloomberg Businessweek believes. "Groupon ... may be able to bolster its growth by adding vouchers for
e-commerce sites," it writes. Seconds Scot Wingo, CEO of ChannelAdvisor Corp.: "With its ability to send discounts to more than 115 million e-mail subscribers, Groupon could attract sellers that
normally hawk their wares on Amazon and EBay."
Wingo, whose company provides services for online merchants, also thinks it's only a matter of time before Groupon brings its e-commerce strategy stateside. "It seems to be working really well, and I'm guessing once they get it to the point they feel good about it, they can bring it to the U.S.," Wingo tells Bloomberg Businessweek.
A few sites that offer coupons online are Redplum and Coupons. You can also get E-coupons at Printapons and possibly at your local grocer's website.
