Well I had to send back a brake pipe yesterday , needed a back one , but turned out it was a front !
Post cost was £1.26
Looked on the net and found the one I need , price was good but as normal there was no post cost !
So ordered it over the phone , was in stock , then he asked for card details /
I asked the total price , it was over £8.50 more then the cost of the part , I told him I am not paying that , he said well you will not get it before Christmas , I said I am not in a £8.50 much of a hurry !
Now it’s coming standard 2nd class at around £3.50 , still over £2 more then I paid !!
Still it is around 2inches longer , ask any woman , best not 
lol
