Lubrication for Prusa I3, where to buy in UK?

Hello everyone, so I'be been reading lots of forums about lubricant and i was wondering, does anyone know a good lubricant for Linear bearings and threaded rods that's easily available in the UK. I've read a lot about the wonders of super-lube, but that's £20 ($30) on amazon, the only place u can really get it here, I'm not paying £20... XD

Does anyone know a good, cheaper alternative?

Many Thanks, Brad

I use wd 40 dry PTFE, available from most diy stores

I've been using a product called sailkote
It's a dry ptfe , low to no odor and sticks to anything you spray it on
We use it to lube the conical and threads on Porsche 918 Spyder wheels
Works very well under hi pressures

I found this in Wilko for about £3. It seams ok, has PTFE and all.

I have the WD40 dry at the moment, it seems to work okay although I'm not sure how long it actually lasts on the rods. I had something similar to the 3-in-one that I bought from Halfords and I think I might have preferred that.

I've been using RC diff lube
