This works best for us.  If the visitor is already a member, we offer a free
class.  We won't open the store until June but that's a good idea as well,
although $50 might be too much for us.  We've also had incentives at our
special events that have been donated:  i.e. ATA donated a trip to the
Bahamas for 2 to give away in a drawing.  We also have a runner-up prize,
which is usually one of those books of food/entertainment discount coupons
and which costs us about $30 to purchase.
