Looking for a 'Wire Harness' for Integra

newbie's here and say HI to everyone first. :)

i just wanna buy a wire harness for installing a new radio in my car. though some ebay guys sell it there at a not expensive price like 3 bucks, the shipping fee is even more than 6 bucks (f*** that!). so i come here to ask you guys whether there're any local stores which sell it at a reasonable price (under 3 bucks)?

or any guys here get an extra one for selling?
