Scouring the planet for donations can be your reason for living some days, especially if you are planning an auction, an awards banquet, a reception, a walk-a-thon, or anything that requires you to wear your fund-raiser hat for the day. Sometimes, a person’s or group’s amazing generosity befalls you, making securing a donation easier than you’d expected. But recipients beware! That donation might come with an unseen string that may actually hurt your budget.
