Why does DDR3 Dimm memory cost so much?

Mostly out of curiosity. On eBay 4 GB ddr3 dimms run around $10.  There must be millions of these around, pulled from dead machines. Seems they should be a lot cheaper. Any opinions?  Know any place to get them cheaper?
Thanks,
Al

There is a bottom price level that applies even if an item costs the seller nothing.  It consists of the time to collect the item, package it, buy the packaging supplies, and either send it out or take it out for shipment.  That would be right around the $5 level.  On top of that the seller must make something, tack on another $5.  There's the $10 price point.

Personally I find it remarkable that people are willing to sell anything on the fleabay at prices that do not justify half an hour of their time.

Cheap memory can usually be had from your local computer recycler, and if you take it untested as-is "for art supplies" it's often free.  (Most recyclers have insurance or legal issues with selling anything "for purpose" which is not tested to work properly.)

RAM has extreme UPS and DOWNs in prices due to many factors...lets say that 4GB RAM for $10 is a great price for the time being...considering the prices a year ago and the lack of any predictions that prices will come down...
I am afraid that RAM along with GPUs have followed the explosion of Cell Phones  + CryptoCurrencies...nowdays mobile phones with 8GB RAM is a natural thing and the continuing stability of Bitcoin (mainly) and its byproducts keeps mining demands....

i suppose a 8 GB stick would be more than double that price...i guess around 40$

The first mainframe I worked on had 8mb of RAM. I guess I shouldn't complain about $10 for 4GB sticks.
Thanks to all,
