No minimum garment requirements.  We can digital print on other garments besides shirts but will need to check prior to completing order.  Orders will not be started until we receive payment on your invoice.  Once the invoiced is paid we will order your shirts which takes 1-3 business days to receive.  Orders will be finished and available for pickup 1-7 days after the invoice is placed.  If we need to ship it we will have to add 3-5 business days for you to receive on top of the production time.  If you need a rush order please let us know in your email.
