Fundraisers: There were LOTS of t-shirts... very few of which really caught my eye. I bought 2. There were scrub bottoms and shorts with sayings along the lines of "nurses kick butt" on the rear end. Some groups sold jewelry (some 'quality', some 'homemade', not that those are mutually exclusive, just a wide variety). There were people selling books and badge holders and stethoscope covers and 'tools' such as penlights, clipboards, even stethoscopes. Sorry I'm not in the groove for new or innovative fundraising ideas... believe me if I could come up with something I'd do it.
One of the neatest things I saw (not a fundraiser) was "matching" business cards for attendees from the same SNA... the "company" was the SNA, but each person had their own card with their own name and position (president, treasurer, member). DO make labels for yourself, to put on slips for drawings in the exhibit hall. Include your name, address, phone, email, school, degree you're pursuing, graduation date, and areas of interest (that's alot of info but you can squeeze it all on there... I did).
