So, the deal is confirmed - the 10% threshold may be temporary so watch this space.
Our contact at B&Q said, "If for any reason a card does not work I need the card number so I can investigate as we have had a few where the customers opened them in stores rather than through the organisation
But apart from that all cards are now set at an automatic 5% discount from today and if they spend £500 it will increase to 10% for the remainder of that month and following month as a minimum.
As I stated this trial is for 6 months with the vision of having a permanent decent offer for the future for your members."
If you have lost or never received a card let us have your address which we will have to pass to B&Q and they will sent the card direct. Tell us if this is a replacement so they can use your old number.
