Cartridge World, an ink and toner cartridge retailer, and Complete Nutrition, a nutritional supplement retailer, have partnered with the National Breast Cancer Foundation to help raise funds for the fight against breast cancer.

As part of the partnership, Cartridge World will launch its “Round Up for Pink Ink” campaign in September 2012 and throughout October, which is Breast Cancer Awareness Month. The campaign offers customers the opportunity to donate by rounding up their sales transactions to the next dollar. Cartridge World said it will match the first $25,000 its customers raise. The retailer also will offer customers a free pink cartridge for every two ink or toner cartridges purchased.

During October 2012, Complete Nutrition will collect donations from its health-minded customers through its “Empowered Pink Out” campaign. The program rewards donors of up to $50 with a store credit of equal value, good toward the purchase of more than 200 Complete Nutrition-branded general health weight-loss and sports nutrition products.
