Sadly there isn't much time for chatting in local photo shops. They're too busy selling digital cameras and printers which is good for them, most of them have transitioned well to modern technologies but this doesn't do much for me. Their film processing is now slow (they wait for enough rolls to come in usually) and poor and their film prices are high. Their paper and chemicals are often expired.
Portra 400 is $5/roll for 120 or $10/roll for 220 at B&H. Don't buy film in Canada unless you like throwing your money away, it's at least 50% more here, $7.50/roll for 120 or $15/roll for 220 at Henrys.
Do you need 400 speed? Portra 160 and Ektar 100 are $3.69/roll for 120 at B&H.
I got a few Pro packs of Fuji Reala 100 for $3.49/roll, 10/2012 dated! That's $17/pro pack while it is $40/pro pack here in Canada, just crazy! More than 100% higher than in the states... Our dollar is higher, distributors take note!
