I could really elaborate on this response, but for the sake of time I hope I have narrowed it down and kept it simple. Feel free to critique my thoughts, Its just an opinion.
I look at selling on RJ or any other internet site with an open opinion. They are basically two types of sellers
The seller, that has to unload his car or parts because times happen to be hard for that moment. Usually the first guy that shows up with cash gets the goods. This type of seller usually regrets selling their items after the sale. But you gotta do, What you gotta do......
The other type of seller is known as patient seller. This is someone who has collected unique parts, a vast amount of parts over the years or is a distributor who, when a person has determined that they have committed to purchase an item, they will shop for pricing & pay the most competitive price found. They will pay the amount listed including shipping charges. The seller will not consider an offered for their offer below the listed price and will not settle for any amount less.
There are two types of buyers out there as well, The person looking for the low ball deal and then there’s the average buyer.
The low-baller doesn't do much repeat business, but is sometimes successful in purchasing parts at pennies on the dollar, but when he list the item(s) for sale he expects to get top dollar.
The average buyer, is always looking for the great deal of the century, but understands that those types of deals are few and far between, He is fair to those he deals with and respects the same in return.
Bottom line is, the worth of an item is what someone is willing to pay for it and what the buyer is willing to sell it for.
