Hi all. Recently went to Chinatown twice for a school project (FYI im a student). Noticed a rather significant amount of photography shops around. Got my 450D screen protector from one of them. Should i consider buying any stuff from them in the future? The shop i went was rather friendly. He screwed up the first protector and immediately replaced it with a second one. Are prices reasonable too or some are like SLS ah beng ah beng one?
