Projekts, Edge St - Nice cool relaxed place with chillout area and a bit selection of clothes and decks and accessories (no shoes tho)
Note, Afflecks Palace - probably manchesters "proper"skateshop with joe gavin, dan cintra and tony da silva in there. Nice selection or decks, clothes and shoes. Just mind out for the weirdos who follow you through afflecks!!
Exit, Oldham St - yea...ok its not a real skateshop and skaters try not to go there since it isnt a skater owned shop but anyway....small selection of decks, shoes and clothes. Only use as last resort!
