I love Charmin Mega Rolls they are huge and last forever! Last month I bought a pack of 24 rolls and I still have about 9 rolls left, which isn't bad for a family of four, with 2 small children.
Amazon.com has a good deal right now on 24 pks. which is like buying 96 regular rolls for only 30.50. You can get it for 25.92 when you subscribe. Don't forget to clip the .25 off coupon for added savings, making this deal as low as 25.67.
