We can print an advertisement, image, or Name onto a Coffee Mug that becomes a permanent part. This is a high quality product that will last and last. Not run or fade like cheaper mugs that you might buy at a sovenier shop. 
 
We use a special ink that does not go onto the mug as a liguid. Instead the ink, is turned into a gas by heating it to 360 degress fahrenheit.  The gas gets into the pores of the mug becoming a permanent part. It is dish washer safe... We use these ourselves and they have never faded. 
 
Sure you might find a internet service that makes mugs cheaper.. But will they last? Ink or paint directly onto a mug will not last like the permanent solution that we use..
