They always have extras in the back. I don't know why they don't put everything out. Last week when I was there getting the oxblood rivets rogue the SA brought out a deleted multi tea rose charm. It was on clearance (70/25) so I ended up getting the $145 charm for $27 since the cashier scanned a barcode to give me an extra discount! If I hadn't started a conversation with the SA about the rogue she never would have brought the charm out.
I always just want to peek back in the stockroom to see all that I'm missing.
