Ag charge £3.50 for lightweight packs such as film. That would make them £25.90 + £3.50 for 10 rolls of 120, so £29.40 total compared to £31.50 at 7dayshop. For 135-36 the price would be £36.40 against £38, but it'll come quicker and you're supporting an analogue business!
Thanks. I'll add Ag to my favourites and give them a go next time I order some film.
