This is how Teepublic describe themselves...
"TeePublic is a curated community of the worlds best designers. Our platform enables designers to upload as many t-shirt designs as they want, create their own store and build a following without having to worry about printing or shipping. When a designer uploads a new t-shirt, it's on sale for $14 for the first 72 hours, after that it's only $20 or $22 for 2xl-3xl."
Teepublic is run by the good people at Busted Tees. So far I have been very impressed by their customer service. They are prompt and friendly.
If you are a designer considering joining Teepublic please use this link affiliate TEEPUBLIC. I would really appreciate it.
