I'll definitely have to check those places.
As for Costco, my local Costco stopped processing any film. Sad.
I got some scans back from Custom Color (medium res scans)... the tonality is not that great and the noise reduction smoothed out ANY detail from my roll of Ilford Delta 3200. Ouch.
My lesson: so far, I haven't found a place that does really good scans that match the quality I'm able to manually do on my Epson 4490. The problem is ... if I shot 10 rolls for an event, I'll be sitting at the computer all day scanning!
