some of the shops are pretty pricey.
there's a shop with kids' clothes that sells miniman stuff - some of that can be a great bargain.
but missoni etc can still be pricey - if you have a favourite designer it's maybe worth it.
i love going round auchan and the ludendo village with the nice sweet shop and toys etc.
if you're just after a wander round the shops you might be better going to paris as you will manage to fit in more accidental sightseeing - you can see the eiffel tower from most places, for example.
