I feel more comfortable buying from someone that list retail at time of original purchase, this gives an idea of the age of the piece. Like Pupul57 said they can mention current retail in the description, bottom line the serial # is still most important but with the inability to email members the back and forth process can be arduous and very slow!!!!
Retail?
When listing an item's new retail, should the price be the current retail, or the price of the item at the time it was purchased? If you know someone bought an item for $2,500, it is 3 years old, and the say the current price is $3,300 and are asking $2,200 - is this appropriate and honest or somewhat not?
