OT: Need advice, how long is too long...

You are most likely SOL, but you can always give it a shot if it is a reputable dealer. I have returned two items for partial refunds that I did not try to authenticate until 1-2 years after I purchased them. One of them was actually a consignment shop, so he would completely be losing money if I did the return. However, both times, I was able to get a partial refund. I did not request a full refund because I did not think it was fair to the seller either, so both times, we were able to come up with a reasonable refund that we were both okay with. However, if the seller says tough luck, there is really nothing you can do because you are past the credit card and paypal seller protections which are usually around a year.
