Remember once a few years back, a friend of mine brought a memory card from one of the staff , then on the next day another friend brought the same memory card for $10 cheaper from Mr Loh. Both my 1st friend and I were at the shop during 2nd friend purchase and I told Mr Loh about the diff in pricing on the same item. Mr Loh refund $10 to my 1st friend immediately and apologized to him. Not sure which other shop in S'pore will do that?
