Staples.com said Tuesday that it has added Staples.com Canada to its Internet arsenal, making it the first country-specific site in its Internet operations. The site publishes in both French and English, and includes country-specific pricing for Canadian buyers. The move is the first in an expected series of international deployments from Staples.com., Framingham, Mass. The company is a key player in the ultra-competitive, highly consolidated and low-profit-margin office supplies industry. Typically, office supply companies have been among the first to test new e-commerce technologies and approaches.
