Not sure if anyone is interested but i came across this site through my work, with some pretty damn cheap deals on World Cup England memorabilia.
They offer free P+P with any order, no minimum order value, so the price you pay is never much more than a quid. Maybe something fun for the kids to have.
Some examples are :
England Supporter's Wristband - 26p Delivered
England Supporter's Hand Held Fan - 74p Delivered
England Supporter's Inflatable Baseball Bat - 42p Delivered
