The company I used last year charged me 140 PLN per sheet. I want to know if it is the norm or if I was ripped off as I'm a foreigner, and if you can suggest someone who is cheaper.
Depending on what you mean by a "sheet", but I'd say that you most probably got ripped off. I think the people I know charge in the region of 40zl (plus VAT) per 1,125 characters (including spaces). Want me to send you their email address by private message?
