"Healthclns" is the "merchant" who bills your credit card company for the trays. The trays are all the same but have different company names. Cleanwhites is one and DazzeSmile is another. They try to confuse you and say that they are not affiliated with one another, yet their "merchant" is the same. I canceled with DazzeSmile who agreed that I had ordered the trays along with the gel applicator. They canceled my order and gave me a cancelation #. I thought I was canceling Cleanwhites because they came up as healthclns also on my credit card bill. When I kept receiving them I called and found out that they are a different complany who also bills under "healthclns" (the same "merchant") So somehow I am receiving the same product from 2 different companies who have the same "merchant" I did order fron the 2 different companies, but when I called the one to cancel she said that they were the same company. A confusing scam that cost me 100's of dollars. Healthclns shoud be looked into!
