I have used photobox for a few different kind of orders and have always either been underwhelmed or completely disappointed.
Even when giving them one last chance when I recently ordered plain old prints and paid for the premium finish (thinking: how hard can that be to get wrong) even then the quality was so poor that I have not been able to use any of the prints. When I complained I received a very poor response from someone who I doubt finished grade 2. Their awnser to my complaint was that I should reorder and pay again in full to see if the prints came out better.
