Only because you're including RAM spec'ed at 75pS access times.

If you limit the selection to 133MHz (the slowest 'max speed' - ridiculous, you can still easily purchase NEW 50nS and 70nS SRAM elsewhere, this is why I don't buy from mouser)...

Then the price falls to £5 for a 32MB (256Mbit) chip, which isn't excessively priced, but it still more than I paid for similar chips a few weeks ago.
