Memory sticks for desktop PC computers. Most of the older memory modules are industry standard; pretty much if it fits the memory slot in the motherboard, they will probably work. Most modules are "unbuffered" except where noted. These cannot be used in laptop. Can be mailed for $3 more per shipment. Not sure what the current market price for the memory modules. If you can use it, make me an offer.
