Hello Nick,
Congratulations on the store! Owning a LFS a lot of work, but building a great community around it is rewarding. Your reviews on Yelp and Google are absolutely raving. I'll have to make a trip up there one day.
If you're looking to purchase inventory for the store you should 100% drive, as it's the easiest way to safely bring home bulk frags. A good amount of people will offer lot deals at the end of the show (buy all of my remaining corals for a big discount). It gives you a great deal and price to work with while also helping the vendors pack up less at the end of the day. It's very rare that you'll be able to cherry-pick 1000s of aquacultured frags from so many different vendors. The variety you can bring home is staggering compared to having to place the usual wholesale wild colony order from a single company. It's like having over 100 different places to shop under one roof, and everyone carries something different. The frags you purchase are also ready to sell, something that you rarely encounter from most wholesalers. Making the initial drive will also prepare you physically/ mentally if you decide to come next year as a vendor (but coming down just to shop could be worth it alone).
You can also fly down to SoCal, rent a car, and drive all of your frags back up. The 7 hours you save on your first day you can visit wholesalers around LAX and other LFS in SoCal. Or just enjoy your time away from the store.
See you this weekend!
