Everyone makes mistakes, but it seems like Groupon keeps making them—and then compounding them.

Take, for example, Wednesday’s deal in the Chicago area. It was for discounted auto detailing; the email came with a broken link.

Oops.

It happens. But if your company is Groupon, and a client is waiting for customers to pour in—but they won’t because of a broken link—you apologize and make up for it.

Enter the follow-up email with the subject line: “We sent you a broken link…Computers aren’t really our strong suit.”

Really? Seems to me that without computers you’d be, well, a daily shopper.

This prompts the question: What is your strong suit, Groupon?

So far, it seems like your strong suit is PR gaffes and offensive (and expensive) advertising.

The continuing stream of mistakes suggests that links aren’t the only things broken at Groupon.
