how to differentiate between a scam and a product which just doesnt work for us?

like makcik A can offer nasi lemak RM1 and say sedap, mak cik B can offer rm10 nasi lemak and say sedap as well.
some prefer makcik A say "it is sedap and murah" and some may say "nasi lemak B is sedap and worth the money." some might find nasi lemak A tak sedap thus "patutlah murah." and some might find out nasi lemak B as tak sedap "harap ja mahal"

when u have the option to judge and choose, i can choose A or B at my will,even tho i might pay more it is my own decision..

if both makcik say "hey buy my nasi lemak, you can cure cancer by eating it 5x/day" regardless they sell it rm1 or rm1000, i can justify it is some sort of scam. false claim.
