Price Chopper has 3 pack O-Cel-O sponges B1G1 @ $3.79 this week. You can sign up for their newsletter and receive a $0.75 off ANY 2 O-Cel-O Scrub Sponges in your inbox. After this coupon is doubled each 3 pack is only $1.15 which is a good price for these sponges. I love the designs on them!
Update: I've read that the $25 and under items at MYHABIT sell out quickly - so you probably want to be on the site right when today's sale starts: 12 noon EST or 9 am PT. You can click on the picture above to sign up and you can scroll down 2 posts for more information on MYHABIT.
