I went to my local store the other day (Filton Abbeywood) Bristol.
And they had:
Smiley face boxers £1.
Range of ties £1
Batman Boxers £1 - (Were £12)
Also got a few pairs of jeans for £5 each, not the best jeans in my oppinion, but they are ok for a fiver, bought a few pairs which were like £40 roughly before each.
Worth a look if you have a store near you :)
