How To Buy/Sell an Android Smart Phone

There was a question posed on which phones to buy under $200 on T-Mobile.  I believe this is the best way to determine market value of ANY smart phone if you are considering buying or selling:


Log into eBay and do an advanced search of specific models. In the advanced search menu, click the "completed listings" box. When you get the list, take note of the sale prices in Green (ignore the red ones, they did not sell). This gives you the range of what buyers were willing to pay. BEWARE: read descriptions of your high and low range, some may be bundled with junk accessories, or "as is/for parts". This range will give you bargaining power if you decide to buy off Craigslist.  Doing this will give you a Real Time look at basic economics (the value of a product is determined by how much one is willing to pay for it).


Side note:  ALWAYS KEEP YOUR BOX AND ORIGINAL MATERIALS!!!  The smartphone box alone could make a $50 difference in the resale value online.
