Afraid it is the old story, the small quantity packaging and distribution for 'hobby' purchasers grossly inflates the price.
Have you checked out aeromodeller and drone hobby suppliers? I don't have a brand name, but understand a very slippy plastics compatible grease has been widely adopted; always a chance that stronger demand in that sector might hold prices down a little. Share anything you learn please, see below!

<{POST_SNAPBACK}>...My Hobby-lube tube has split and ended up with dust in the grease.
So it's happening all over the world then. I bought a Hobbylube pack of seven (ultra light, light, gluey gear, oils; Moly grease, PTFE grease, graphite and PTFE powders) must be 20 years ago, and two of the tubes fractured early this year wehn I picked them up to use them. What's left of the contents all now transferred to glass sample tubes, but dispensing is not so convenient. (I do feel I got my money's worth, as all have been used in many different applications beyond model railway, and some were nearing 'all gone'. News of alternatives thus welcome.
