I have a large number of rolls of undeveloped 35mm file (over 100). What are some places I can find that will develop these for a reasonable price, and ideally digitize them for online download at the same time? So far the cheapest I have found is York Photo, who will develop the film + 1 set of prints for $4.50 (includes S&H) + $1 to digitize the photos. But I have no idea of their quality.
Currently (July 2010) in the UK:
Certain Costco locations do develop & scan (3000x2000) to CD for ~$5. You'll have to call to see if one near you provides it.
