Depends what you're looking for. Essentially, browse the classifieds of the fauna persuasion to get an idea. Some things are WELL worth it. Example, my Brazilian Rainbow Boa. $300 at my local store, $100 at Repticon. Mad savings, but I only had to drive an hour. Not sure how far you're traveling.
The CRBE is definitely well worth the visit whether you're looking to buy or browse. I can guarantee the CRBE's prices will be lower then any pet stores around here.. Have fun. I know I'll be there.. It's a 4 hour drive for me!
