I've found myself getting very good at finding things as cheaply as possible - or even for free (even better!).
I went to the local salvo's store (I have found a new one right near me!) and found this great little table and chair set for $15. I was so excited, telling the shop assistant exactly what I had planned for it - she very politely pretended to be interested :).

Also ages ago I was driving around and came across a pile of logs that had obviously been cut down from a tree lying on the side of the road for council clean up. I felt a little weird filling up the boot of the car from the side of the road - but not enough to stop doing it :)
