Simple – specify what you want your job printing on beforehand then you get what you ask for.

The point is most ‘cheap’ printing is a fixed deal and aimed at small business owners who don’t have the knowledge to realise the differences.
For example those business cards from Vista Print that are about £5 but actually some random size not 85×55 as a business card should be.
The other thing is to advertise ‘flyers’ when you actually get 130gsm which is a leaflet to any real designer or printer.
oh and to the OP…
based on your spec above I’ve just saved you £50 or more… http://www.facemediagroup.co.uk/?page=budget-leaflets
