That may explain the steep price. The Brick and Question Mark block extensions — in 1ft to 6ft configurations — go for just $20, but the actual USB drives that plug into the extension are $55 a pop. The mushroom, goomba and koopa drives are still for sale, but it looks like the Mario one is long-gone.

Get 'em while you can and hopefully before Nintendo finds out.
