Hi J.,
On rare occasions, I have called in response to a car magnet ad. I remember one time in particular, I called about a magnet I saw on a minivan for a child's arts and crafts "indoor playground". I have to wonder how effective the magnet was though, since sadly, they've gone out of business. The magnets are pretty inexpensive so it may be worth a shot...Maybe consider asking local daycare centers, schools, some pediatrics offices and other businesses that cater to children about whether they might allow you to leave a flyer on their bulletin boards or maybe just business cards in their lobbies. Good luck! It's tough out there right now :)!
