Toilet paper printed with advertisements will appear in the bathrooms of the Port Chester-Rye Brook, NY, Public Library in October, according to The Journal News. Venues that use the paper receive it for free, making it a potentially attractive way for cash-strapped libraries to reduce spending. (Advertisers pay $99 for 20,000 advertisements that appear on approximately 160 rolls.) It may sound silly, but little things add up: According to EducationBug, the library must stock enough toilet paper for 180,183 annual visitors (plus a staff of 15). Plugging that figure into Kimberly-Clark’s professional use calculator yields more than 36,000 cases, meaning the library could be saving $70,000 per year or more on the deal.
