Definitely the gas thing! Maybe a big faux-gas station sign with 0.00 for a price instead of 4.xx? You could have Ours vs. Theirs at the top or not. That might be attention getting. Would just take a piece of posterboard and some spray paint and construction paper for letter forms. You could model it after a local wellknown gas chain (without the name, so you don't get in trouble) but so that people know.

Thanks so much for doing this, you guys rock!
