Need Paint? your local rubbish tip might have a "PaintBack" bin where people throw away perfectly good full tins of it.
Paint has become very expensive in recent years - I should know, I'm a painter by trade. I try to keep some paint for the next job (like Whites and Primer that I know i'll use) But it often sits in my garage for years until eventually I drop in the local "PaintBack" bin for old paint at the tip. The other day I was dropping some off and noticed a nearly full 10L of Dulux Precision ($250 worth) that someone had left there - YOINK! you're coming to a better home little buddy. Now, are you really allowed to take paint out of there? I didn't ask - but it would be a crime against the environment not to. I'm sure there plenty of nearly full 10L Whites and Primers that go to waste. If you're not too fussy about having the latest fashionable White you could be lucky and find enough for a whole room. I'll keep a closer eye on my local one. Some people really overestimate how much they'll need and then just throw it away.
