Where can I buy used items, such as a bicycle, food blender, etc.?

I looked on the Florence classified section of this site, but nothing seems to be there...am I doing something wrong, or is it just not used much?  Anyway, would love to get some inside info on where I can buy some things used, as I'm on a budget and may not be here longer than 3 months, so don't want to spend a lot on small appliances...Thank you, for any insight.

The open air 2nd hand markets usually on Saturdays in nearest town.

thank you - I will try!
