This place is severely overpriced compared to other print shops in the area (or the whole city for…read morethat matter). I just paid 2,50€ for one single 300g A3 print (which I ended up throwing out because the colors were printed incorrectly).
The service is very lacking; it's supposed to be self-service, which is fine, except the printing software does not allow you to change very basic settings yourself, such as setting the correct color profile. This basically means that if you print images or graphics with color, it will very likely come out looking wrong. You cannot change these settings yourself, but if you ask, the staff will still just say that they cannot help. I'm not sure they even know of these things.
And it really ticks me off that if you print, say, 50 pages, and you have a few test prints that comes out wrong (because of the above reasons) you still pay the full, overpriced amount for every single page. Any reasonable store would have some sort of good-will discount in those cases.
Would not recommend this place at all.
