I just read the article in the Business of Design Magazine about using gift cards or gift certificates for clients.  I like the idea- have tried out the certificate a couple of time, but so far no takers.  I really like the idea of giving out a gift card as an incentive.  I've seen something like it in a very high-end type of magazine, Robb Report I think, for a jewelry store.

Has anyone else done this or have any ideas?
