First do your homework !! Check prices on ebay, Craigslist, and any other similar selling sites you can think of !! Know before you go what you can get similar and within driving distance !! Then go make them a reasonable offer for your area !! Yes they have to make a profit but I would bet they didn`t pay over $50. for that one !! If they refuse your offer just thank them and leave your phone number in case they have a change of heart !! Chances are they will deal on it !! Even though they are selling cheaper here and in other areas you have to take your time into consideration !! I would offer $150. if they are hard to find in your area !! If they don`t deal or call in a few days, shop around !! Take your time and don`t jump when dealing !! Just know your stuff and what a reasonable selling price is !!
