I constantly come across this issue. I find a decent pair of Oakleys on eBay or another site but the seller doesn't have the box or papers. This usually brings up a red flag in my mind, but a lot of times it seems like the seller just didn't think you needed them or they were worthless. I guess the box and papers only really bring value for collectors. But how do you decide how much value it adds or subtracts. I.e I'm looking at this pair of Jordans: http://www.ebay.com/itm/Oakley-Mars...76545394?pt=US_Sunglasses&hash=item20d2db5e72 and they don't come with the Aluminum box or papers. This always makes it hard for me to value a pair. How much do you guys think the box/bag/papers is worth for a normal pair/ a rare pair. I.e Penny's vs. OTT's?
