Can anyone tell me where there is an art supply store in Madrid? I'll be arriving on Sunday and I'm desperate to find oil paint and turpentine.

Thanks,
Carole

The best shops to buy art suplies are in Hortaleza street, close to Gran Via (maybe it could be Fuencarral, I'm not sure, it's the enxt one). They're not very big, but have almost everything and the best prices.
