For just straight vinyl lettering on a teeshirt, like a football name and number, I get $15 including the shirt. For anything off the Versacamm, $20. Sweatshirts would be $5 extra or more.
I have noticed (I use Specialty Materials) that digital print transfers don't hold up well in the wash-after 8-10 times through it starts to fade off.
I also have combined digital print (photo) with screenprinting for lettering around it. Screen first, apply decal last.
Customers loved them.
that sounds like a great combo..
