Questions: In regards to back of the room sales, if there are 100 people at a lecture, what percent of the people do you figure I should have books ready to buy... and then what do I leave behind for them to order when I run out?
Do you have the name of a company that makes post cards reasonably?
Answers: How many books you will sell depends completely on how good a speaker and promoter you are. There simply aren't any average numbers. Plan on bringing one case. If you run out, promise the other people free shipping if they place the order with you right then. Leave a catalog or sale sheet for those not ready to order then.
