Check your 7/1 P&G coupon insert for a $1/1 Ivory Soap coupon.
This is actually a great one because 3pks of Ivory Soap are about $1.25 at both Target and Walmart. CVS has the 3pks for $.99 every so often as well so you can get a fantastic deal on bar soap.
Kroger puts the body wash on sale 10/$10 every few weeks so that might be another option for you.
Stay tuned because I have a really fun and incredibly simple craft project you can do with the kiddos using Ivory soap.
