Im in Australia, retail prices here are just ludicrous! We have one huge photo retailer here called Vanbar, they sell pretty much everything photographic. its the only place you can really purchase BW film and chems in Melbourne, Victoria at least! Ok so...i put up an order on adorama for 80 rolls of 120 film (20xTrix,20xdelta,20xhp5+,20xFuji) the total WITH shipping to me form the US was around $450USD, which is $432AUD. i racked up the same bunch of film using Vanbars prices, and with PICK UP it was $780AUD!!!!
Ebay is out of the question as its only a little bit cheaper than vanbar. However i do regularly pick up expired lots form ebay for 1/4 retail price and i have yet to be disappointed! i have a fridge full of 35mm 100ft spools!
