Who would be the best (cheapest) courier service to use? I have used Greyhound Bus Freight in the past but how would they go with mags? Not packaged?

Pack and Send would be by far the easiest. ive used them a few times before.
to get a 60a sent to perth from brissy was bit over the 100 samolian mark.

i used TNT had a set of mags with tyres sent from sydney to nyngan 600kms away $88 ,
i no its not interstate but it give ya a idea

Pack and Send Eh... Theres another to give a go. I need to organise 5 rims with tyres. That is assuming I buy them... They are not Jellies though. I may just cry myself to sleep tonight.

Pack and send are the way to go! they are by far the easyiest and the cheapest in my opinion.

A mate of mine is a truck driver for TNT and he sold some seats on ebay and he said that pack and send is cheaper then TNT and Pack and Send used TNT to send the seats! go figure that one out!

try these guys, door too door and cheaper than pack and send as well as greyhound usually here

I have used Unique expess a few times.
$70 to send a 60 series gearbox packed in a vegetable crate . 72 hours Perth to Brisbane
nice people to deal with. They can also move complete cars at about the same price as the car carriers BUT you can fill it up with all your spare parts

Pack & Send.

I wouldn't go as far to say they are the cheapest out there but they do what they do well.

I had no drama's when I moved all my household items.
