A few months back, as a test, I sent one roll of 120 color and one roll of 120 C41 b&w through Walmart to Fuji for develop only. I was quoted $1.84 per roll. When it came back two weeks later, the color was $1.84 and the b&w was $9.00!! The WM clerk called Fuji and was told "That's the way it is with B&W". Instead of running it with the other C41, they "sent it out" to a local "pro lab". In my experience, Walmart readily makes adjustments for this kind of error, but not this time. I was SOL. I can have 120 color processed nearby, in three days, for $5.50 roll. B&W, I do myself. OK, I'm thru now. 🙂
