I buy jars from Plasdene as well (luckily I live a couple of suburbs away) and sell 250gm jars for $5 each.
Because it is a hobby for us, we donate all income to charity. Long story but when my son was born he was very sick (fine now), so we give it all to the newborn ambulance service.
Pre Covid, I?d take the jars in to my work and leave them in the kitchen on an honesty system, with a sign making it very clear that all money received went to charity. I?d still get around 10% stolen each time. It?s been harder to shift this year, but have a few regulars and a local naturopath puts in the occasional bulk order.
While it?s a bit of work for us extracting and bottling, the tax deduction for the donation each year certainly helps. The fact it is for charity and we make no money from it tends to stop people whinging about the price.
