You could drop it by at wal-mart. Not the 1-hour kiosk, the send-off kiosk. You should be able to just drop off the film in an envelope. Put 120 rollfilm in the special instructions box, and whatever size prints you want (if any).
C-41 is standardized, so unless you need push/pull, high-res scans or fast turnaround, it doesn't make sense to use an expensive pro lab in my opinion.
I'll second the vote for Dwayne's. I am currently waiting on a long overdue order with Dale labs. With Dwayne's a roll of E6 I mailed on Monday was back to me on Friday. My order with Dale labs is now 11 days and counting - and they charged my credit card 7 days ago.
I'll report back if the quality was worth the wait.
In life you only get one great dog, one great car, and one great woman. Pet the dog. Drive the car. Make love to the woman. Don't mix them up.
walmart (eg fuji) is fairly careless with send-out 120 developing. They always include the end of the roll with the staple in it, in the envelope of negs. often results in scratches/impressions on at least one image where it rubs it. Morons.
