We raise money for chairity at work and we have contests to see who can raise $500 -$1000 in a month. Some things we do to motivate eachother charts with our names and amounts raised,free lunch for a weekly winner,free coffee for a weekend winner,$50 gift cert for monthly winner,having the boss wear something silly if we raised $300 in one day (he rocked that pink feather boa). It seems competion and bragging rights sometimess go along way
