I have some kind of special circumstances, so I have come up with the following:
My direct supervisor won't write for me, as I would leave the company upon matriculation, so I have worked with six coworkers and friends in writing for six schools. Some only wrote for one school, others wrote for up to three. As such, I want to give gifts somewhat proportionally to effort expended.
I am giving each person a shirt or sweatshirt to the school they wrote for (this is around $25-$35, appropriate) and in the end, once I am accepted, I will get each of the six a nice pen, perhaps engraved. I figure a pen is appropriate considering the nature of the task. It does feel a bit weird buying school-branded stuff before I am accepted, but I figure that since I'm not the person wearing it it's not as weird. I don't know if any of them will wear it, but the response so far has been good (better than with chocolates, which I gave to my Wharton recommenders).
If they like it, go for it, but this seems strange to me. They have no reason to care about the schools they are recommending you to. If someone asked me to write them a recommendation to the University of Michigan and then bought me a Michigan shirt, I would feel compelled to burn it. But that's just because Michigan sucks.
