Clipper Grease?

[Nasicus]

I've just bit the bullet and ordered a Lister Liberty Deluxe pack (pretty decent prices on them at the moment), and reading the manual in preparation, I see it says to grease the gears every 6 months with Lister R2 Grease.
I know it comes with one sachet, but from what I can tell this is only enough to do it once, so I've tried to find some more sachets but the only place I can find it wants £3.80 for postage on even a single sachet, and I know that sounds crazy as I just dropped £400 on clippers, but I don't want to spend that postage

So, are there any other greases that I could use that wouldn't void the warranty on them? I'd be sending them back to Lister for sharpening and servicing, do they grease the gears for you there? Or has someone managed to get some sachets off of them perhaps?

I want to take really good care of these and do it all properly

Good point, I do have hoarder tendencies, it wouldn't be out of sorts for me to order 5 years worth of sachets at once haha!
