I had to pay £65 ($130) for a 256MB stick of PC100 memory the other day

I was upgrading my sister-in-law's PC, despite my best efforts I had failed to get her to provide me with the Dell tag number for the PC (I bought the PC on her behalf some years ago, but couldn't remember which model it was). She lives in deepest, darkest North Wales (5 hours drive from us).

So I couldn't buy the memory until I had seen the machine and the only place I could find locally was PC World...
