Gifts? (2)

I've decided to try an experiment, giving each of our company's full time employees a $100 budget to select gifts of their own. The restrictions are that the gifts must not be for friends or co-employees and that the employee must document who, what, and how much is spent to receive reimbursement. Employees are not required to spend the money -- any surplus will be donated to charity. Other than that, I am not putting any restrictions in place.
The thinking here is that gift giving is something that works best if based on real knowledge and connection; so it needs to be decentralized -- and that if we are building a healthy business culture, we should not put all of this in the sales department's hands. The budget is low enough (this year) that I don't need to justify it in the planning process/cycle.
