Just to bump this old topic, my front left is getting prety worn and i've got a long trip this wed/thur/fri. Went on etyres, booked a day/time, then stuck in my card details, pressed finish, and it just went to a blank page!!
So phoned them up and they said they have no way of telling if the order was placed, but i could do another over the phone and they'd cancel the first one if needs be. So went through all the details again, and they charged me the £65. Then a few hours later I get a call back saying they can't process my order as they don't cover this area!
Ended up going to the local tyre place, only semi-decent thing they had in stock was a Givslad thingie....
