They have pretty quick turnaround, too. Most days I've gone in there I've left the job with them and they've had it done within half an hour.
Officeworks have competitive prices also. They start of at 8 cents an A4 copy. But you have to get several thousand done before they come down to 5 cents.
The advantage with Officeworks is just how many stores there are around the city, plus the fact that you can do the copies yourself. However many stores have had issues with the self serve set-up in recent months. It's something to do with the sleek new copying systems they have had installed. Many times I've gone in there and the machine you use to add value to your card has been out of action.
But they seem to be solving that problem now -- though some locations still have issues. The ones I've found most reliable are Fremantle, Subiaco and East Perth.
