To a firm with the slightly dodgy title of leathersrus, Parcelforce & our very own MM...
Following a post on here, ordered a front wheel chock from Evilbay 24/1. Then realised I had not used a £5 off code. Mailed the sellers, had a mail back within 5 minutes saying it would be honoured & my card credited with the discount.
This am, 27/1, it arrived, via PF. Looks to be a solid piece of kit, same Xtron model as MM showed in his pics, & as a bonus my cats are happily asleep in the box.
