hmmm i dunno.....
Its the same as anything in this world. If you have an item, that other people want, and they are willing to pay... why not....
Same way as if someone buys a car in japan, imports it, and sells it to make a profit.
It like any other business opportunity.
Maybe its different in perth, but in sydney personalised plates have a $360 per year fee to have, so selling it at a higher than cost price can make sense I suppose, to cover costs.....
