A tin of Imperial Die Wax will last for many thousands of cases. The cost is irrelevant as is the amount in a tin - you only need a touch per case due to it being so effective.That’s a reasonable question: as a hobby, and rather like we try different case/powder/bullet combos, lube is another area I’ve always queried its cost given how little you get!
By comparison spray lube (proprietary or home made) is quite wasteful but can be very handy when lubing a large batch of cases.
Amazon has lanolin & IPA.
