Grand Opening Ideas

We recently opened a coin wash for the first time. In about a week, we are looking to do a grand opening, and wondered what ideas anyone could offer to help us get up and running at 8 turns a day! (just kidding, but it would be nice). We are offering a drop off service (no delivery yet). We are located in a heavy rent area, mid campus to a state university of about 24,000 students.
The town size is about 40,000.

Food. Gift certicate form that student can mail to parent, who can return it with money. One price to wash all the jeans on a dorm floor. Same for white socks.
