At first blush, the T-shirt business looks like a sure thing. All you need is a bunch of blank T- shirts, a wall full of jazzy transfers, and a heat press. You can buy blank shirts for as little as $1.60 apiece and stock transfers for $1.50 a shot. That's a $3.10 investment. Sell the shirt for $15 and you've got a nice, fat profit margin. What could be easier? Trouble is, everyone knows the formula. In fact there are dozens of websites that offer not only the necessary supplies, but also sage advice on how to set up your T-shirt shop, either online or in a real store. They all promise you can get rich selling T-shirts. T-shirt shop owners aren't so sanguine about getting rich. Quite simply, there are far too many T-shirt shops and online outlets. The competition is fierce. So T-shirt shops have to battle for customers every day. As a shop owner in South Padre Island lamented, "Every day you have to compete with other shops. And if you invent something new, they will copy you." Source: Industry websites and news, 2015.
