Staples offers the Charmin Essentials Strong Toilet Paper Giant Roll 20-Pack, model no. 96609, for $7.99. Opt for in-store pickup to avoid the $9.95 shipping fee. That's 40 cents per roll and the lowest price we could find by $5, although we saw a 24-pack for the same price three weeks ago. Each roll contains 300 sheets of 1-ply toilet paper.
