If you have a Marxist theoretical background (whatever that is) I suggest passing those two very relevant books for something else instead:

His "Towards an anthropological theory of value" (or however its called at libgen). It does try to revise Marx theory by building up onto smart "women-anthropologists" before him and to search about how value is generated in money less societies and how everyday-interaction does produce and reproduce society and as such value concepts.

I understood what was written as kind of a good lense to look at his other works in some situations. Also it can be read on a weekend and is pretty clear (unlike Marx).
