Amazon offers the Charmin Ultra Soft Mega Roll Toilet Paper 18-Pack for $16.98. Clip the $2 off coupon on the product page to cut the price to $14.98. Plus, Prime members bag free shipping. (Non-members can spend $35 or more to qualify for free shipping; otherwise, shipping costs $10.58.) That's tied with our mention from last week and $2 below what you would pay locally.
