Yup. $115 shipping $144 GST (I bought a bunch of Bren mags as well).
I did think the shipping charge was a 'little' high...
I shipped a sub200 gun cp and it was 50$ insured with signature and proof of age privately. Its $2 for ever $100 in value. I wouldn't put it past it for a oversized package/weight/possibly insurance. Not sure how some places can still ship for free they must work out a good deal. But terms also usually say they aren't responsible for lost/damaged if you do not pay for insurance.
