Yes. What most kids fail to realize is the process that goes into making a shirt, let alone 6 different designs like that. Some may remember when i produced and sold some customs on here like 8 months ago. I was asking 25 shipped and could barely get anyone to buy them, sadly. Blank, high quality shirts are your base price. Colored shirts cost more than white shirts. Then you have the design labor to factor in, along with the number of colors in each design, amount of ink, and how many individual screens it takes to get the final product. Then advertising and calculating the right number to produce with a small markup in order to make a profit. Many other small details along the way too. Id say those shirts are most definitely worth $30.
