Building a Following Friday: Merchandise
Don't sell merchandise for your book until you have fans! That seems harsh, but highschool soccer players don't have their own clothing lines but Cristiano Ronaldo does. Do you know why? Ronaldo has fans. Lots of them. A highschool player has some fans, but not enough to justify spending tons of money to produce merchandise.
Merchandise is really cool, but remember that you're trying to make money rather than to spend lots of money on cool stuff. Unless you already have a fan base, no one is going to buy book merchandise. It's a simple piece of advice, but believe me, it can save you a lot of money.
