Hello All - Tks for the input...
There are some supermarkets, the biggest one is at Railway Terminal. I would recommend the Tiramisu there too, cheap and good.
Fontain water - hmmmm...dont quite recommend it, cos I saw someone washing their feet there...lol
I would certainly recommend a 1 Day Tour for Tuscany if you are not driving. U may check out this site, for 95.88USD u can explore Siena, San Gimignano and Pisa, lunch and wine tasting all in 1 day.

U can take a bus from (I remember) Florence to San Gimignano and Siena, both quite near. Pisa, I think I took a train. No need to waste money on tours
Good to use 70-200mm in those towns except for the patio in Siena
