It really depends on the kind of market that you are going to buy products which you would have the opportunity to bargain on prices before you buy it because if you go to supermarket to buy such products, there is no negotiation of price.Bargaining in Nigeria when trying to buy a thing is very important . Because even the sellers will expect this from you. if you don't you get cheated and bug the item at a higher price. I haggle a lot with sellers and have a good buy at the end of the day as I would be buying at a far lesser price. Do you practice this in your country?
