Hi,
I clipped the code from the listing and looked at it on my code tester. It indicated there were missing closing tags for a Table element.
I worked down thru the code and my best guess is missing </td>/tr></table> on the section for the PayPal logo. I added the tags on the tester, and the alignments immediately snapped to normal. It's possible the closures go a little further down the code, but that was the evidence that confirms a coding error with missing closures.
You should be able to locate the code in the active listing and modify with eBay's Revise listing editor. The sequence of code is the anchor tag for the logo followed by a Javascript tag. I inserted the closures just before the <script...> tag changing from this:
payments for your eBay purchases!">
<script type="text/javascript">
to this:
payments for your eBay purchases!"></td></tr></table>
<script type="text/javascript">
Use Preview before you complete the Revise, and see if that's a good fix.
