Hobby Lobby usually has a coupon on their website as well (they will also email it to you every Sunday morning along with their ad for that week if you sign up for their mailing list).The small blocks of melt and pour base are 2 pounds and sell around here for about $11. The soaps I made are about 4 oz each so you can make about 8 soaps. I buy my soap base at AC Moore & Michaels using the 40% or 50% coupons they have in their ads each week (you can also print the coupons off of their websites). They also have larger 5 or 10 pound blocks too. The only other thing you need is color & fragrance. which is inexpensive and a little goes a long way. You can buy commercial molds for a couple of dollars or make your own molds.
I miss having an AC Moore around. It was always my favorite between those three.
