It is hard to tell if the vendor is a fraudster or not. Fraudster is the person who commits fraud. Some fraudsters uses internet to do their dirty tricks. Some force you to pay advance bill or a down payment for the parts you are going to buy. Some offers original price but fake parts. You should be aware of these.
You can tell if it’s a fraudster or not buy checking their license, permits and other legal papers supporting their business. You can also ask feedback or testimonies to your friends or other people about that vendor if it’s a fraudster or not. Also if there’s someone walking in your front door and selling small car parts like seat belt, seat cover and mat. It is convenient but it may force you to buy something that you don’t want or something that has poor value and quality. Sometimes it may result to over pricing of the parts.
Be careful in choosing the right vendor or else you will suffer the consequences.
