http://stores.ebay.com/radiantwild comes up just fine and shows your items. The redirect from your domain does fail as you describe.
That means the problem is in the redirection setup at your web or domain host, even though it looks ok as far as I can see. You have it set up as a 301 permanent redirect, and the URL looks correct in the in-browser HTTP header caps I did.
Tried another test using the full URL of your domain (http://www.radstockvintage.com/), it tries to redirect to http://www.stores.ebay.com/radiantwild and fails over to http://stores.ebay.com
Choosing wrong type of www redirect at domain registrar when you redirect domain may be the issue here:
In the “redirects to” field, enter the full URL of the page to which you will
be redirecting.
Select one of the following www redirection options to dictate whether or not
the domain will be redirecting:
* Only redirect with www. only redirects visitors that type www. as part of the URL.
* Redirect with or without www. redirects all visitors regardless of if they use www.
or not.
* Do Not Redirect www. will not redirect visitors that use www. as part of the URL.
Clicking the Wild Card Redirect option allows users to set up a redirect to the same
file on a new destination.
* With Wild Card Redirect, www.example.com/about.html will redirect to
www.example-destination.com/about.html
* Without Wild Card Redirect, www.example.com/about.html will redirect to
www.example-destination.com
Click Add to create the redirect as specified.
Fix the www redirection issue at GoDaddy and it should work.
