I am a painter traveling to Italy this summer. I will arrive in Florence late on a Saturday and travel on to Perugia the following morning. I am looking for an art supply store in Florence that is open on a Sunday and carries oil painting supplies (specifically the things you can't carry on an airplane, like paint thinner). Can anyone help me with this search?
Zecchi is probably one of the most famous and most likely to be open on a Sunday. Not the cheapest though.

Otherwise you can try:
Rigacci
Or
Baccetti
Or also
Bati
(Google the above names and Firenze to see their websites)
I know some in my old neighborhood but I don't want to send you far from the city center. Art supply stores are everywhere in Florence.
Otherwise, if they are all Closed on Sunday, buy them in Perugia. They'll have plenty there too.
