i don't know about your stores.. but my store and my SA (south coast plaza boutique) tells me it's ok to SO small leather goods.. for instance, a suahli 'pochette', multicolor pocket agenda, multicolor porte valeurs..
however, longer straps for a certain purse i dont think is available.. but they do sell straps separately if you'd like to purchase those extra.
