Please don't add linebreaks at the beginning of the serials. I noticed on multiple pages that you're adding a <br> at the beginning of the serial. Follow the format we've always been doing. Only use it when there's multiple lines. And if there's a Special Edition, just make it between <small> tags.
Example
SLUS-10000<br/>SLUS-10001<br/>SLUS-10010 <small>(Special Edition)</small>
Result
SLUS-10000
SLUS-10001
SLUS-10010 (Special Edition)
