I use a company called Amsterdam to order pens imprinted with my company's name and website address. This company has a good selection and decent prices. The thing is that the website prices aren't as good as the prices I get in my catalog. The quarterly catalogs have items *much* cheaper and with lower minimum orders than the website. You can get pens with printing on them for like 19¢ - 29¢ and such. There are also keychains, magnets, plastic cups, lanyards, mousepads and things like that.

I'm not a guy, so I have no idea what would work for your fraternity and/or IFC. Actually, these things might be better suited to a specific fraternity as opposed to a general IFC marketing tool. Though, pens with a catchy recruitment slogan and your IFC website address would be cheap, handy and actually useful for the recipient.
Just an idea!
