They did one last year - hat and scarf with initials on. We bought some for Christmas presents, they were very well received. Always try and buy charity cards as well.
Yeah, they get a lot less publicity than Great Ormand Street or Manchester Children's but any and all Childrens Hospitals deserve a share of the pie when it comes to charity. Fair play to Matalan. I go past Alder Hey on an almost daily basis, the grass idea for the sides of the buildings might have been great in the minds of the kids that were part of the design team, but it looks impossible for the grass to be cut or renewed because of the gradient and it's looking rather untidy at the moment. Kids eh. what would we do without them.
