If you're just look for develop only, do Costco. Avoid places like Rite Aid, or Walgreens like the plague. Believe it or not, the vast majority of Costco's revenue comes from their Photo dept. So they hire people who take care of it.
Walgreens and Rite Aid don't. Most of the employees don't know what a densitometer is, and they never run control strips in their Noritsu's unless something goes wrong, like 5 roll of film came out blank. They almost never clean the filters, rollers, or top off the racks. Trust me, of all the cheap places, Costco is the best, BY FAR.
