We are thinking of using Tiffany Town Car and stopping at Publix to pick up water and a few other items. My question is this - usually I stock up on bottled water when I see it on sale and then pack it and bring with me. Will it be that much more expensive to get it at Publix? It would be nice not to have to carry all that water which is heavy, as long as their prices are reasonable. Anyone done this who can help me?
