When you think about where things are found, there are plenty of options to consider and things that might come to mind in the process.  The person might look in a phone book to see if there is a retailer in the their area for the item they want.  Someone else would immediately go online to find exactly what they desire.  Personalized T shirts are available in lots of different places so there are plenty of options for everyone.  There are places that will specialize in a certain kind of shirt that might appeal to someone who is looking for that special shirt.
