Outdoor plant pots

[annie8]

I am trying to build up the number of large plant pots on my deck to put my flowers in. I prefer ceramic or terracotta to plastic. Can be expensive though, is there anywhere people find a good source of these?

By behind office blocks by the skips.
I have picked up several that way.
It is usually the bigger ones where they can't be bothered lifting them in.
They usually come with a tortured plant already in them.
