The decision to cut the promotion short angered hundreds of followers of the grocer's Facebook page and prompted the following apology:
"We at Marsh recently stuck our toe in the water to try this whole social media thing. Unfortunately we ended up stubbing it. Our recent $10 coupon offer on Facebook has instead left us red in the face and many of our loyal customers angry. Rightfully so. For that we are truly sorry."
The company began offering the coupon last Tuesday to its "loyal fans, customers and employees" on its Facebook site and told them "don't be afraid to share. Marsh would love to see more shoppers become fans."
But by Friday, Marsh announced on its Facebook page that it had rescinded the promotion, which was supposed to last until Aug. 8. The chain blamed wide "unauthorized" distribution of the coupon for the cancellation.
Marsh has 3,051 followers of its Facebook social-networking site. Such sites are becoming a powerful marketing tool for companies to reach consumers.
