AstroSM North Edsa has stocks of Superman 3 and 4 when i passed by yesterday.
Thanks for the info. However, I was already get a copy each this morning at Radio City Megamall. Nagtanong ako sa Astro Podium pero wala pa raw sila. So, I decided to go to Megamall and the first store I went to was Radio City, and they already have it on display. I later went to Astrovision, and they also have copies of it.
At last, kumpleto na ang collection ko -- I now have
Superman I, II, III and IV! Maitatabi ko na rin 'yung III and IV kong PDVD. Hopefully, by next year, kasama ng ng collection ko ang Superman Returns DVD (siyempre, original).
