Trellis for delivery?

It's hard, in fact nigh on impossible to transport two 5ft by 6ft trellis fence panels in a Renault Clio. That means we'll need to get them, some fence posts and the post stakes delivered (OK, I know they would have gone in the car!). Twelve pounds for delivery from the garden centre, twenty five pounds from Wickes and they aren't available for online ordering from B&Q. In fact both the chains I mentioned only had 6ft by 6ft, which is too large. So the garden centre it is then. 

Next to find some time during the day to phone through the order.
