E-Go.
Simple and easy.
Its cheaper if you get it dropped off to your nearest depot rather than to your door.
You can basically get everything sorted on your end through e-go and pay it.
Then email the person who is sending the wheels the paperwork for them to printout (so they must have a printer available) and get them to put the paperwork into a plastic sleeve and wire the sleeve onto the wheels somewhere.
That's it.
A courier will pick up the wheels from them and then deliver it to your nearest depot or to your door, depending on what delivery location you chose when you organised it.
You can track the wheels from the E-go website.
Don't forget to write mobile phone numbers down for the seller and yourself.
Ive had wheels done before and they arrived on a small skid pallet.
If the seller goes to their local Bunnings or Masters home improvement stores, gets a small wooden skid for free, they can wire or strap the wheels onto the skid ready for pickup.
Usually the truck driver will have like a hand trolley or something to help pick it up.
But the other alternative which is cheaper again, is to have the seller deliver the wheels to their nearest transport depot (take wheels and skid separately), then strap it all onto the skid at the transport depot. That way a forklift can pick it up straight away. You can find the nearest drop off depot to the seller from the EGO website. If the seller is willing to deliver it to the transport depot, that saves you money again.
