AmbergrisCaye.com Home Forums The Cayes Ambergris Caye Grocery Store open on Sunday afternoon?

I'm scheduled to arrive in BZE at 3 pm on Sunday, so my arrival in SP will be probably a few hours after that (sooner I hope). Will there be any grocery stores open late Sunday afternoon on the island or do they tend to close down? I realize I'm leaving the US where 24 hour grocery stores are common!
