There was a problem some time back with their lye. Many, many soapers were having issues, the soap just stayed soft and oily, same recipes and same oils. The only variable was the lye. These were experienced soapmakers. Some of the soapers said they had the lye tested and it was only 48-52% pure.
As more and more people had problems, and more and more people contacted ED, the customer service and eventually the public relations got worse and worse. First the company said there was nothing wrong with the lye, the soapmaker must have made a mistake. Then when so many complained, they said send us the batch numbers we will look into it. When some people demanded that ED replace the lye, they refused. They have never admitted any fault as far as I know.
That is the BIG reason I have heard that a lot of people refuse to do business with them. There have always been issues with sometimes the customer service is good, sometimes it isn't. Some of their prices are excellent, but beware of ordering essential oils from them, they have started selling dilutions so make sure you know what you are ordering. If they get your order right, great. If there is a problem, they are not the easiest company to deal with getting it resolved.
Beware of the shipping charges, you can look at the website and see "FREE SHIPPING!" but the exact same item costs 3 times what the not-free shipping product on their own site costs.
