So I finally bought a late 2012 iMac and immediately upgraded the RAM. Now I want to sell the RAM that came with the iMac (branded Elpida). Usually I sell my stuff in Amazon, but I just realized that to create a new listing I need to either find the same product in their store (they don't have it) or provide the UPC/EAN/GTIN code. Problem is, I cannot find anywhere the UPC code for part number Elpida EBJ41UF8BDU5-GN-F. I'm guessing this is stuff they sell to Apple but not to the public. Any of you had the same problem? How/where did you sell your RAM?
