I have used Groupon to advertise my business in the past and the only reason I would give them any stars is because their platform engages a large audience. Beyond that, Groupon operates a business that is not only unethical, it is crossing the lines of engaging in illegal practices. I strongly urge any business thinking of working with Groupon to use great caution! Groupon allowed an advertisement to be posted using my company name and business location without my permission. Not only did they post an ad without consulting (I operate a sole proprietorship) but they absolutely refused to take it down when I notified them. I was told that as long as someone operates as a sub-contractor, they can advertise using any business location they chose. Groupon did not request or receive any documentation to show an affiliation with my company or location. When I spoke to Groupon and told them that I did not have a sub-contractor working with me nor did I want anyone advertising that they worked out of my business location. I was told there was nothing that they can do. They refused to take it down. I am baffled that Groupon allows anyone to sell vouchers without requiring proof that they are in fact a legitimate owner or employee of the advertised establishment. Not only is Groupon promoting false advertising, they are potentially creating false reviews for an unknowing company. I truly hope that The Better Business Bureau looks into this practice further as it could be detrimental to small businesses.
