I've been using Print24 for years and have spent thousands of pounds with them... simply because I cant find anyone else... but now I am desperate to find another printing provider.
It's hit and miss whether your product will turn out the way you desire.
Their customer service is bad. Any 'mistakes' are always the customers fault.
Their artwork uploader is confusing and unhelpful. Beware the 'screenproof', if it is not right call them don't just re-upload as it goes straight to print without you getting to proof it again. This resulted in the layout of my work being printed wrong.
I also made one order then, a few months later, ordered the exact same thing and it came with completely different finish.
I'm very upset and angry. They do not care about their customers.
(This review comes from a very friendly, understanding person, who never leaves bad reviews, but I have been hurt too many times by this company and wish to warn others.)
