I also had a similar question. I know he sells through the other websites but they're sold out too. For example - I'm looking for a Metallica topper. Seems hard to find online and the ones available aren't lasseriffics.
That new GB one looks sick btw.
EDIT - to the poster above, I will let OP of course get first dibs but if he doesn't want a MET topper and you have one, I'm interested. Thanks.
