Ok, i have been using O3 Jollop for the last year (And good it is too) but my bottle was running out so i sought a cheaper and less conspicuous alternative.
I came up with this.
I have it on good authority (From the person that formulated Jollop) that this is essentially the same thing. There is a little added antiseptic but that's about it. The company that makes the Agri-Gel is the same company that makes Jollop for O3.
So how much is it? Well i bought a 500ml bottle (The smallest in the picture) for about £2.95 Jollop is not all that expensive but it's about £5 for a much smaller bottle. Something like 250ml so it's almost 4 times more expensive.
