empty (or nearly) 5 litre paint cans, damaged is fine (Highbury Barn N5)

I need up to 8 empty (or nearly) 5 litre paint (or varnish) cans - ideally plastic, not metal. I can get rid of up to a litre of paint if they’re not completely empty. It’s fine if they have holes or cracks.

Please reply with a postcode so I can plan my journey and an idea of convenient pick up times/dates. I’m also looking for a couple of 60cm sq paving slabs – mentioning it here just in case. They don’t need to match so I’d be glad to take just one off your hands if that is all you have.

Thanks for reading.
