Publix at Rock Springs and Welch Road in Apopka had it about a month ago-we were thinking about Strawberry Rhubarb Pie for Pi Day (3/14), but ended up deciding on chocolate and key lime instead. I haven't looked for it since then, but they may still have it, or other Publix stores may. If you have a neighborhood Publix, check with their produce manager-if he or she doesn't have it, they may be able to tell you who does, or make some calls for you to find out.
I'd also try the Fresh Market in Altamonte Springs on 434.
Good luck.
