Van hire @ Ikea

Looking at the frankly appalling stories people are having with IKEA online ordering at the moment, thought that hiring a Hertz van myself (they have partnered with IKEA apparently) to get a couple of sofas home.

Anyone have any experience with this? What was the process involved? To get the family card price can I still preorder?

Either that or buy some roof racks for my yeti.........

Thanks
