Hello Vivien,
We’re glad you’re happy with your purchase, I am sorry for the disappointment regarding the voucher. The £5 off code requires a £70 minimum spend, and as this wasn’t reached, our system issued the next best applicable discount instead — which is why you received the 5% discount code to offer you the £1.92 saving.
Any questions please email us on info@locksdirect.co.uk
Kind Regards,
Hollie
