I noticed that Florida had the best deals on giant fish tanks. It actually lead me to try a insane plan to buy a giant 180 gallon plus tank while in Port Canaveral Florida. And then bring the acrylic monster on board a cruise ship that sails down from Baltimore Maryland in a giant loop.The cost difference of the giant tanks in Florida compared to Virginia are so massive that they could easily surpass the cost of the cruise.
As for why I plan to use the ship instead of driving down to Florida is it's cheaper and faster to take the giant tank on the ship then to rent a U haul.
But have not tried this idea yet even though there is a rule that as long as it fits into your cabin you can take it with you on the ship.
