Yes it is possible, at this stage though not at all feasible. It may be something I can look at in the future how ever. To make one with alcohol I would need to use a formula with up to 30% alcohol volume. Technically it would not be allowed to go in the post. When I first enquired about it with Australia Post they said no way.
Squadron, Vshod, artisan arcade etc all post aftershave in express options and some of that must fly instead of go by road. It's a pretty loosely enforced rule. Some pay for accreditation? to send theirs I believe.
I've got tons of Avon but had the occasional seller say pickup only due to the rules.
