Amazon offers the Quilted Northern Ultra Plush Double Roll Toilet Paper 48-Pack for $23.94. Add it to your cart via Subscribe & Save and they drop to $22.74 at final checkout. With free shipping, that's 47 cents per roll and $1 under what you could expect to pay at a local Walmart. (We saw it for $2 less in January.)

Note: Be sure to cancel Subscribe & Save once your order ships to avoid being billed for subsequent shipments.
