The tooth soap looks like a good product. They sell a tooth soap that is plain so that you can add whatever essential oil you like at any given time.
Be careful with some specials. They might be products that have been siting on the shelf too long and they are trying to get rid of them before they expire/discontinuing the product. I usually like to order products directly from the company and I make a request to send me the product with the latest expiration date possible. This way you get the freshest product possible. This is important if your ordering anything that is food based…fish oil, coconut oil etc..
