i think au natural have gone already (of sorts)
ratners and the likes next,
property dealers (as yet unmentioned on here)
agree jjb sports wear and equipment,
up market clothes shops (jigsaw, coast, monsoon, laura ashley)
music retailers (hmv, virgin, any cd suppliers)
agree, smiths (nothing anyone else doesnt do)
pier, coffee mug makers, 'fussy bits' shops no one really needs but buys, bhs, tammy girl, mark one, some 'card shops' comet/currys/pc world, maybe one of them,
it is depressing...
