There is a lot in FB that selling item below market price. For example, a Shimano fishing reel where is standard market price is RM500+ is selling at 200+. Scammer in order to persuade buyer is giving COD option. But this COD option itself is a trap because the seller is using 3rd party courier.

From this, U actually no able to open the package to check because the moment U open it, it consider sold even the item is not the genuine product.

U either ask courier can check the item before paying or not only (which 3rd party courier doesn't let U to open it without paying first)

If U see item below market price on FB. U can troll back the seller by order it then cancel the order afterward. Let them bare back the deliver cost

This delivery + COD method is more like scam, they might simply give you something cheap and you cannot reject the item, but you have to pay the delivery guy in full. And you cannot take action against the shop, but if you are purchasing online and you did not receive your goods as per the shop then you can report and withhold your payment to the shop.

COD stands for cash on DELIVERY which means u pay upon delivsry of item to ur place.

Malaysian bastardized this term where u pay when u collect the item from seller. Thats not COD. thats COC, cash on collection

Not really. Tons of courier offer this service.

anyways i always cod if i buy something from facebook marketplace, meet the seller, inspect the item, some seller even let me use the item for few days before pay. if all ok then pay cash or online transfer witnessed by both of us on the spot

the key here is "meet the seller"
