I've got a couple of things to post and can't find good size boxes.

Usually I get something from AusPost or from Officeworks, but in this instance their sizes are no good.

In order to fit six scouts or one alternator I need to buy boxes that are too big.

I could fit 12 scouts in this box!


The six fit almost perfectly into smaller box except the lid wont close



This box is almost perfect except Nemesis Prime's box is too tall


What other choices are there? Where do people other get their boxes from?

I have had ebay wins sent to me in shoe boxes. Is that appropriate?

Can I cut up an oversized cardboard box to make two smaller better fitting sized boxes to post? Or creating new folds in these boxes and filling the gap with other cardboard?
