Hmmm.... matching prices is a good start but a subjective one. Just like Carrefour, they have the same policy ... but in order to prove, have to show competitor's price from ads or prints.... which is not practical. Cheap prices are never on print ie. negotiated.

So how to prove negotiated price from competitor?

From experience, better price are found from electrical or smaller shops. Just the other day, asked Mediaplex about Denon 1930 player.... when they mentioned RM2500, I almost jumped back out the entrance. The first price I got over the phone (not even bargain yet) from shop in SS2, was RM1600.
