FONDANT!!!

Hello everyone! I am in the Navy and I have been trying to plan my boyfriends birthday party but I have been underway for weeks! The party is now Saturday and I have everything else ordered except for the cake! I can make my own cake, but I need somewhere where I can buy fondant! I have no idea where to look, everywhere I have looked is closed on Sundays! (perfect, the day I get back). Any suggestions?? Anywhere that sells fondant on the Sunday would be great!
