considering 512 modules were selling for mega hundreds not all that long ago, even when the prices off 256meg and below modules where reaching these incredible lows, it is completely understandable.
look at the 512 prices for the vendors on pricewatch that haven't updated in awhile, the ones at the end of the list, makes for good reading.
sales are down, and prices will drop again, hopefully.
i feel memory is inflated as far as price goes anyway, hell, we are talking a rather small PCB, all made to industry standards, then the manu/assemblers install the chips.
a lot less goes into a memory module than building a motherboard or CPU, just for an example, so, my take is that for years they have been RIPPING us off!!!
