Looking for inexpensive ways to improve your workplace? Try bartering for perks. For example, James Morel, the president of 1-800-POSTCARDS, a $4 million New York City-based postcard printer, bartered with a health club for free gym memberships for employees. One note: for tax purposes, 1-800-POSTCARDS has to track noncash transactions like bartering. You'll have to do the same.
