The prices aren't too bad here. I use a fairly expensive "1 hour place" and they charge $3 for the roll and .35$ for each 4x6. So $8.25 plus tax. A roll of 36 35mm 4x6 is $10.68 with tax! I don't take much to them, but they are the best 35mm processor in town.

my local sams club does my 120 film inhouse for me. works great. i get it back in 20 min. costs me 1.58$. if i send it out it costs me $.51 and takes about a week to get it back! not too bad, and cheap enough.
Different country and all, but for processing only, I go to KMart. They do processing only for $2.50 (the pro lab I visit charges closer to $7 for processing only), uncut.
I prefer this, because when I get prints, I get my negatives scratched to hell and back. Then I can scan the negs myself (a quick batch scan on the flatbed gives a good enough idea) to see how they look, then either scan in on the dedicated film scanner, or take to my usual pro lab for an enlargeent.
In Marlboro, MA, I pay $8.00 a roll for develop only 120 (I've been using XP2 lately, too). 35mm is maybe $6.00? I use a mom&pop type place, so others may be cheaper. They can develop, but not print, 120.
