I've been looking at the pricing structure of an online printing service, and have noticed that there are are significant savings to be had by sending them one file consisting of multiple images to be printed, and cutting them myself, rather than getting the images printed and cut into discrete photographs.
For example if I get 100 6x4" photos printed and cut by them, they will cost £102 (Edit: I realise this is expensive - the site is primarily focussed on larger sized prints but the pricing structure for smaller ones illustrates my point better here) . But if I get them printed in one 600x4" panoramic image (this is possible), and cut them myself, they will cost me £36.00. This immediately justifies the cost of buying a fairly decent paper cutter.
My question is: are they likely to be annoyed by this approach? I don't believe this changes the way they will print the photos, as I think they print them on a roll, and perhaps there is a cutter built into the printer. All I am doing is not paying them quite a large sum to cut the photos.
Has anyone tried this, or at least something similar but perhaps less extreme?
NB: It looks like a fairly large-scale operation.
