Just checked Littlewoods this morning when making a return and noticed they have 2 Wii's available. One is delivery in 3 weeks (with wii play, remote & nunchuck) at £259.00 and the other is the wii with sonic secret rings & sport pack for £269.00 which states delivery within 7 weeks.
Not sure how likely their dates are but I ordered a PS3 not so long back and was meant to be delivered later this month but arrived this morning!
I know a lot of you won't deal with Littlewoods anymore...but with Christmas coming up I thought it was atleast worth a shot to get a Wii for your child (or you!)
Really hope this helps someone!
