Go to an ag supply store. Bigger bottles but a lot cheaper overall. I have been buying quite a few of the 'apparent' and 'surefire' br
But do your research, some things are no cheaper. eg you paid $17 for 250ml of bin die ($70/L) Surefire buffalo is $75/L.
Regarding glypho, its a good example of grams per litre being $$$. You got 450g/l high strength. You got 450g of 'pure' glypho for $50.
I can get Apparent 'concussion' (they have funny model names) 540 for $50. Thats an extra 90g of pure glypho for the same price. I can get Surefire glypho 540 for $35 at my local ag shop, but they tend to be fairly cheap.
While you are at the ag shop - pick up a 25kg bag of ag grade epsom salts - mix it in about 2kg with every 8-10kg of fertiliser. Works good. Bunnings have it in 1kg packs for $8. That means $200 for a 25kg bag.
25kg bag at an ag shop - $35 max. Theres your mark up.
