These are all a decade old and easy to find.
I try not to be cynical but if you are trying to source components either as a hobbyist or procurement professional and ARE NOT using one of these easily found sites then you are getting goosed.

Maybe, but my volume is so low and orders so infrequent, it doesn't really matter if I pay $1 for an IC or $0.5, so I usually just go with what either is the most convenient (eg sparkfun breakout boards) or the quickest shipping (Farnell has free next day delivery for me). Having said that, these sites are great resources and I do check every now and again.
