Well done and thank you in developing roasted ground wattleseed, and helping to introduce it into Australian homes & restaurants. I've certainly had an interesting and enjoyable time cooking with wattleseed and eating the results.
You do have a point in what you wrote. However, I wish to highlight a couple of other stores to Wattleseed10.
(1) You weren't able to email the website you mentioned above as they hadn't updated their new email address. As I'm a customer of his, he emailed me his new email address below, but it doesn't appear to have been updated onto the website, though I did inform him (Lyle Dudley) of this a while ago.
Lyle's store sells & delivers roast ground wattleseed at very cheap prices compared to some other stores, and he offers to sell any amount, so you don't have to buy by the kg. I am unsure whether Lyle has any business registration (it's best to confirm it with him), however I've bought his roast wattleseed and have been very satisfied with its results in my home cooking. (I have also bought & tried Vic Cherikoff's wattleseed with complete satisfaction).
(2) The following store sells and delivers roasted wattleseed in 1kg lots or 100g lots:
They are a commercial company with an ABN and Food Licence.
(3) The following sells and delivers ground wattleseed in 1kg lots or smaller amounts:
[Note : As a home cook who would go through more than a small packet, I feel it preferable to buy wattleseed at bulk prices ie 500g - 1kg amounts as it is far cheaper than buying small packets long term.]
