I was throwing around ideas to generate some new business this season, and thought about getting some gift certificates made to sell to potential customers. I was thinking of making them for a maximum $25 amount, and have them expire six months from the purchase date. With Father's day coming up, I though it may be a good gift to give "the guy who has everything". Has anybody tried this? If so, what were the good things and the bad things about them? Thanks in advance for the help.
