If you're not in a hurry the 3 day service in Boots is good value at 5 euro. Got some films developed in Spectra lately and thought the quality had gone down and the price up.
I shopped around and found that in Dublin centre, the best place is the chemist on Grafton Street, at the corner with Anne Street. There is not much difference in price compared to Boots (around a euro cheaper), but they throw in a free roll of film. €10.50 for 36 exposures, as far as I can remember (July).
I found that the postal development service is good, but you must pay p & p for each roll, which defeats the whole purpose of saving money.
I'd had similar issue with Spectra, I didn't realise the "standard" size of photo was now 5X7, not a 4X6, of course you get charged extra and the qulaity wasn't great.
Are photosave still using the pink envelopes? I got one a year ago but wasnt sure if it would still work or end up with my films being lost somewhere in deep Kerry!"
