We use Kerrin all the time. For business cards we first used the well-known on-line printer everyone knows, and found the result to be too generic, too commonplace. Moving on to a higher end on-line printer, we found the results fine, but very expensive. Nowadays, Kerrin gives us those same cards at less than half the cost(oops, I hope they don’t raise the price!). They had been referred to us many times before we actually started using them, and now I see why.
