Used this a couple of years back but they have bought it back…
Buy anything (no minimum value) from Halfords before 19th April and claim a Free MOT.
See here… Free MOT | Halfords UK
I saw that too. I assume any purchase will do.
Yes but with 20% of meguairs products (plus oc 10%) as well I’m probably going to have to spend more than my usual £5 or so to get the voucher 
Will they also give us a oc 10% on top of the 20% off ?
10% off the MOT too.
Not if you get their free offer !!!
