Make sure you upload your custom artwork for shirts, hoodies, etc in PNG format and do not leave a background layer. Any layer remaining on the image will print directly to the shirt and we will not issue refunds based on user error. You may be wondering why customizer shirts are cheaper than our product line, consider the artists salary and branding costs. Not to mention we were sure to leave you margin for resale. Shipping rates are dependent on quantity of shirts so make sure you do the math to make the most out of your experience. Feel free to email us directly with questions you may have about this service.
