as frequent buyer of SD cards for my digital movies and photography, i looked for best prices, here is one place to buy Valued SANDISK memory cards both FULL SD and MICRO SD's - many thanks to Qxpress for delivery too.. Thanks to Seller here -- I had visited this place SUSEO Building.. when I was living there...must add - so much bigger than Singapore's SIMI LIM,,,in Seoul is YongSan is best for such electronics stuff.. Seller is from 서울 강남구 수서동 수서타워 / SuseoTower Suseo-dong, Gangnam-gu, Seoul . NOTE: no local warranty by SANDISK Singapore...or the Three Local retailers, due to Serial Numbers.
