Fundraising ideas for the office?

We're just a little office (25), but we like to have money for employee birthday flowers, special lunches, etc. With this few people, I'm looking for ideas on how to raise a bit more petty cash from within.

Fundraising ideas for the office?
There are so many things to do...do you have a BJ's or Sam's Club, or some place available to purchase items in bulk? where i work, we sell candy bars for $1 each. we purchase @ BJ's. of course you would need start-up cash. unfortunately, it takes cash to make cash, but buying in bulk can be a good way to start. is your office open to the public? that way people coming in could also take part, although if it is just used for inhouse events, i probably wouldn't go there. we do it for the United Way, and we have signs posted stating where the funds are going. we also have about 150 employees, and the public helping. maybe, you could start having employees contribute a certain dollar amount a month or year that would help to cover some costs. cut the birthday flowers down to a single rose, to be able to have more available for special lunches. the person who just had the last birthday will be responsible for providing the cake for the next birthday, homemade works too...with a small office it will be harder to raise funds from within...you could contact a tupperware dealer (or some other item that there may be an interest in) in your area to discuss fundraising. the employees could have their friends and families make purchases and your office would get a percentage of the sales.
