What do you do with old nursery pots?

[natasha]

I have loads of old nursery pots. The pots that the chids come in. I will repot my chids as soon as they finish flowering, to check on the medium and for aesthetic purposes - I love using terracotta coloured plastic pots. However, I have kept the old ones, except those that are damaged. I am wondering what should I do with these stuff, since I don't think that nurseries here will buy back the old pots.

I am sure you guys must have some back in your stores too, and wondering what you did to them?
