The exhibitors at Jamboree often offer discounted prices on memberships, computer programs, books, etc. I’ve held off buying some books knowing I might find them at a lower price at Jamboree. I’ve looked up the prices online and added them to Evernote. While I’m at Jamboree, I can compare the prices to those I save in Evernote and buy accordingly.
Though you can save money at Jamboree, you’ll probably end up spending more with all the great stuff you’ll find!
