I've been using e-go.com.au as part of my ebay business for some 3.5 months now to freight cartons around Australia. The prices are absolutely unbeatable and have made my business viable. The services offered are a little pared down; for example, you can't call regarding your booking, but you can email via the form on their contact page and they are extremely responsive. I've contacted their support via email a few times (to correct/alter orders) and their service was excellent. All packages have always arrived on time or ahead of schedule, and in over 50 deliveries I've never had a customer complain about how packages have arrived. I strongly recommended this freight business.
