I take mine to Sainsbury's where it costs £4 for dev and scan to CD.
I've never noticed this at my local Sainsbury which is a pain because my local Asda have just taken out their bike racks so securing the bike while I pick up my film is a pain in the ...

Anyone used the above people for 35mm? It's £4.95 for dev including reasonable res scans to cd and includes return postage.
When my local supermarkets fail to provide secure bike facilities I like to put my bike in a trolley and push it around the supermarket with me, it foils even the most determined thieving scallywag.

Calumet also comes out cheapest for a 5-pack of Portra 160. I was quite surprised at these results; I've ordered some Precisa from dfd and a bunch of BW/Portra stuff from Calumet!
Just did some 35mm film price researching yesterday, and I was surprised that 7dayshop came out the most expensive per film on Provia, Tmax100/400 and TriX. Like £7.07 for Tmax100 vs £3.97 from Calumet's ebay shop (free delivery in both cases). discountfilmsdirect do the best low quantity prices for Agfa Precisa (around £6.50 per film for >1), but AG photo do the best bargain for that film (£42.90 for a 10-pack, plus £4.90 delivery). Calumet also comes out cheapest for a 5-pack of Portra 160. I was quite surprised at these results; I've ordered some Precisa from dfd and a bunch of BW/Portra stuff from Calumet!
And if you live near a branch or warehouse of Calumet then you can pick it up from there for free, shame that the Nottingham branch went a few years ago as back home its very useful being able to order film etc online and then just pick it up the next time me or my parents are going into MK. Their prices on T-Max and Tri-X are very good if your able to pick it up.
Never knew that...are they any good ?
My local one does a great job. The scans aren't high res, but they're sharp with plenty of detail. It's a 2 day service, so I'm not 100% sure if they send it to Fuji UK or they do it themselves.
