It looks like nearly every boutique on Chapel St are having sales;

Dakota(right opposite the Jam factory) have some great bargins with up to 50% off brands like Nudie and Adidas.
Morrisey are having a nothing over $99 sales.

And at platapus(I could be spelling it wrong), have the Stan Smith Adi-Color series for around the $179 mark :)

It's Platypus I think?

Anyway, thanks for the tip-off Allan. I'm certainly going to try and get to the Morrissey sale - he does some amazing clothing!
