I had the worst experience buying from this vendor. I was cursed at; had a calculator almost thrown at me; and told I was stupid because I wasn't orientated properly on a serger machine. I had always had success with this vendor until I had to return something that I thought was defective. It wasn't. I just needed more training (which I had to pay for). I would have still purchased the serger from them if the customer service would't have been so bad. They have it clearly marked that they accept returns within 30 days. I had only had the serger for a few days. I have never been cursed at before by customer service. I don't curse and found this distasteful.
