My first shipment to FBA was pretty small, 6 books and 1 video game.
Video game was Tomb Raider. It was sold within a few hours of going live. Previously, I have sold popular video games on Amazon but shipped games myself to buyer. That would normally take a few days to sell.
Then 3 out of six books were sold within first week. One of these books was listed for less money as Merchant Fulfilled previously for many months.
Well so far I am in red. But I sent my second shipment this week. This contained 19 books and 1 kitchen item. Looking forward to seeing how fast the new books sell.
