HI Paul
i have had some NCR carbon copy a4 sheets deon, 1000 quantity, (these are my quote forms) these come in pads of 50 , cost = £98 (top white copy is customer copy, bottom yellow is my copy) printed two sides as well
10.000 A6 Full colour postacrds £124
Ring peter at gp print, 01733 340 622
www.gp-print.co.ukand ask for further details, he is a
quality printer, and is now doing "print share". so basicallly if you club together with another business your costs are massivly cut, for instance: we just shared with 3 other business that peter has on his books and we all had full colour post cards 10.000 for £109 300gram gloss,
(ask him for more details)The cost and quality is far superior to other print companies that i have used.
(including ones mentioned on here)you'll find him refreshingly helpful and he will budge on price if he can! free design & pdf proof etc
i do hope this helps you out,as i know how frustrating it can be to find a good printer that will work with you, not against you, if you understand me!!!
