£32,000 winners

“I didn’t even know my husband played the Postcode Lottery. Without that win we could never have Grayson.

“And we were so happy it was Sarah carrying him. I have known her for two years now – and Grayson will always know his Aunty Sarah. We were delighted that someone was prepared to do this for us.”
