Update: In a tweet today, Walmart told Samantha Ficco, “We’re so embarrassed we may never stick our head out of our shell again! Thanks for guiding this lost Terrapin back to MD! -Sonny.”

Original: Walmart is getting a lot of flak for selling T-shirts promoting the University of Maryland Terapins with an outline of Massachusetts. The mistake surfaced last summer on Twitter and again last week by Samantha Ficco, who added a photo of both states in case Walmart needed a geography lesson.

Ficco’s tweet got more than 1,500 likes, 1,300 retweets, and a response from Walmart that only makes matters worse.

Standing by its reasoning, Walmart is still selling the Russell Athletic T-shirts at its stores, The Washington Post reports. The retailer and Russell Athletics have yet to respond to inquiries from DCist.
