Solved Difference Between A Stock And B Stock

Chosen Solution

I’m about to order a replacement bottom case for my MacBook Pro Late 2011. Not sure what the difference is between A and B stock and why is a 14-15"-ish piece of aluminum $150? Thanks in advance!

Prices on anything are based on supply and demand. As to grading. Think of Miley Cyrus in a hot dress and with make-up. Grade A Now think of Miley with no make up, zits showing and dressed in a burlap sack. Grade B Same thing on the inside.
