Right now, Amazon has the 18 pack of Charmin Sensitive Toilet Tissue for only $18.91 once you have clipped the $2 coupon (or possibly less if you select Subscribe & Save). Dermatologist-tested, clog-safe and septic-safe, these 300 sheet rolls are the gentlest option from Charmin at the best price we have seen. Remember, Amazon prices can change at any time.
