Instructions:This came with my clubcard vouchers this morning. The website lets me use the coupon, but instead of deducting £7.50 it only deducted 1p. I've rung Tesco & they said there was a technical fault with that voucher & to checkout as is. I'll be charged full price, but if I ring afterwards they'll refund. If anyone needs to place an order anyway then it might be worth giving this a go.
