where could I buy Prince clothing and jewelry besides bidding on ebay? I know the NPGMC used to do it but since it's been shut down where is the next best place?

thats exactly what im looking for....any one help on this one please?

You should try eil.com.
they have lots of merchndise.

...and madhousemusic. Both them and eil aren't cheap though, some stuff ends up cheaper on ebay, but good as a guide.
