Here are some of my favorite places to shop for soap.
Anderson Soap Company

Mini soaps! They are the perfect size for gifts and little guest soaps. I had a lot of them, but Adam got a hold of them and somehow he can use a whole bar in one shower. I'm starting to think he eats it.
I also love their Anise soap, smells like licorice. While I hate licorice I love the smell and you smell like licorice after you use it. I bought Adam some PBR (Pabst Blue Ribbon Soap), which may have not been a good idea. Now his breath and skin smells like cheap beer, bleh!

Adoration Soap
You need to try the Moroccan Fig Soap. Smelled so good I almost ate it!

Ok, this is shampoo not soap, but it's the best shampoo ever! I don't have anymore which is why my hair looks worse than usual.

Trillium Soaps
Trillium is a local soap company. They sell their soaps in a lot of local stores and have a store in Rockland.
68 Crescent Street
Rockland, Maine
207-594-5003
At their store you can get bags of soap ends. Last time I knew it was $5 a bag and you get quite a bit of soap. If you don't care how pretty your soap is that is.
