Went to a shop in Lucky Plaza to buy a LCD screen protective film for my camera. Last time I bought it in a shop here was $13. I went back to the same shop but they had run out of stock. So I went to a neighbouring shop to buy. This guy took out the same thing that I bought before. The price tag showed $39. I shook my head and wanted to leave. He asked me why. I told him it was too expensive. He then said "ok I sell you $30". I told him that I bought it from neighbouring shop at $13. And he said "ok, loh!".
Guys, do not go to Lucky Plaza if you do not know the price.
