[Sussex] Is there a shop selling just locally produced things in central Brighton?

[Perry's Tracksuit Bottoms]

Also the Sussex Peasant travelling farm shop is all local produce - it's in Preston Park on a Saturday morning near the corner of the bike track

Try one of the Tate's Garden Centre places - for example the one at Hassocks has a decent food/craft retail section that has plenty of local stuff
