£45 seems a lot to have on one coupon. Have they divided them into separate coupons ? If you phone them, they will help you with queries : 0800 591 688 is their Freephone number. I usually save mine up for a couple of years, multiply by four, and get some jewellery at Goldsmiths. For free !! Make sure you use the vouchers before the date is up. you send them off with the form at the back of their brochure and they will send your free voucher for wherever you want to use them. I have also used them for free Days Out to Tower of London and MMe Tussauds.
