You advertise the job you need doing and how much you are willing to pay and then interested couriers ring you up. Its good because you get a dedicated van so size and weight are not an issue and they all have insurance of about £5000 so that covers pretty much any part you need to send. It’s free to use and you can get stuff done really cheap, I got a full IS200 interior from Bristol to Manchester for £45 – impressive! It can take a few days to get it covered so you might struggle if you need something urgent, but on the whole I thought it was excellent.
