I purchased a set of wireless headphones which didn't work properly. You would think it would be easy to do an exchange, not exactly. After a drawn out process, I got an exchange started. What I DIDNT notice in the small print, is your not actually doing an exchange, you are returning your product in exchange to get a new product, with the small print saying that if the new product is also defective, you will ONLY get a credit towards groupon, you will NOT get your money back. So needless to say, the 2nd pair of headphones didn't hold a charge, had ear wax on them, music already stored on them, and the charging cable looked like a dog chewed it up... absolutely disgusting! I will never order Groupon again, they do NOT stand behind their products.
