Not necessarily ! When it comes to sourcing products in Asia in particular.
In order to get your business amid cut-throat competition, the supplier initially lowers the price deliberately to outdo others oftentimes to the level where reasonable profit margin is very thin,or even non-existent.
The likely outcome of this is that he will subsequently deliver a product made with cheaper and inferior material and/or with scaled-down dimension/size to make up for his “lost” margin.
A seasoned buyer, before commitment, makes sure that he has a clear understanding of the cost involved and related market info,plus a good check on the background of the supplier for reliability and reputation.
At times, he even ups the price asked for to ensure goods are properly made with reasonable profit for the supplier.
