We need to buy a large suitcase and not finding luggage shops in Positano. Does anyone know of places to buy in town or in the area? We are also heading to Pompeii tomorrow, any places in that area to buy?
My suggestion is to ask at your hotel.
Maybe have a look in Salerno or Sorrento.
You'll be able to buy a suitcase in Sorrento. On a recent trip I recall seeing luggage for sale near the main square, Piazza Tasso. I think the shop was called De Liso at 9 via Correale, but double check that with a TI office before going. Any tourist information office or hotel can point you in the right direction to a store that sells luggage. Good luck!
