Turns out I calculated postage wrong on forks as only pair I have sent to date was over 2kg.
New much lower rate on rigid forks. Potentially down to £10. Forks between 1kg and 2kg £15.
Splitting suspension forks over 2kg into 2 packages may also give a slightly cheaper postal rate than sending as one package.
If postage prices put you off buying one of my forks, then maybe they're of interest after all.
