pick and choose items from each site, somethings are in line as far as price, others raise question. These websites have been really good staples for me and the sevice is alway a plus.

If you’re planning on making cold process soaps you can get many of your ingredients right from the grocery store.

Olive Oil, Lard, Crisco, Grapeseed Oil. Castor Oil can be purchased at the Pharmacy. Lye from some hardware stores (in the plumbing isle…must say 100% sodium hydroxide or caustic soda)

As for online suppliers, here are is a link to a page I made with tons of suppliers that sell everything you need for making soap, whether it’s cold process or melt and pour.

New Directions has really good prices and a large selection.

Mountain Rose herbs has pretty good prices, especially when you take into account that alot of their stuff is organic.

From Nature with Love has a large selection as well as good prices too.

Check out the link….there are over 50 great places to get supplies from. You should be able to find a place fairly close to you (saves on shipping).

Good luck and have fun!
