Do's: Bring an adequate sized Cooler and some heat-packs, Make the rounds quickly when you first walk in to create a game-plan on which Vendors have Livestock you are really interested in, Bring cash in smaller bills so as to make it easier for Seller or plan to buy in increments of $20's, Bring a notepad or record short video clips on your phone as to the name and any pertinent info on any Corals bought, If you love Blue light bring a small Blue/UV Flashlight to check out Corals that may not be shown under Blue, Be prepared for receiving your Corals once home by having space available and a Dip and inspection process already to go. HAVE FUN and Learn what you can.
Dont's: Don't leave Cooler or Money at home unless this is part of your budgeting plan, Don't initially play hardball in negotiating with Vendors/Sellers wait until towards the end to make offers on package deals especially from ones you did earlier business with, put down any ones purchases no matter what they may be except Aiptasia and Mojano's then tell them nicely they were wronged, forget to throw a few dollars at Club's Raffles.
