One thing to watch with the Halfords trade card: If one of the items your buying is on special offer it can be cheaper NOT to use the trade card for that item.
Due to the way Halfords till system works, if the trade card is scanned through it will cancels a special offer price, put the item back up to full price & then takes of the trade discount.
The till software isnt smart enough to work out which price is cheaper if somethings on offer.
Been exchanging emails with them last week over this issue.
