Right now on Amazon you can get Quilted Northern Bath Tissue Ultra Plush Double Roll, 18 Count for $8.60. This ships free with Amazon Prime or with a $25 purchase using super saver shipping. So I guess you could pick up three to get to that level. This is out of stock now, but you can order now at this low price. You won’t be charged for it, until the product is shipped.
This comes out to 48¢ per double roll or 24¢ per single roll.
Thanks, Couponing to Disney!
