Do your research before you go to a dealership and make them an offer. It's not good to keep bargaining all the time. Your becoming more greedy. If the dealer says okay for 27.5, u will start thinking about 27. Just be a man and take a deal. You might pay 1k more on one stuff but pay 2k less in another thing. This is is life, dude so just embrace it. You don't have to get the cheapest deal all the time. Indian people used to this kind of bargaining when I was working at a store during my undergrad. All the store employees hated Indian it and no body wanted Indian people to come to our store.
