When @richard and I wanted to start selling mugs and t-shirts and all that junk, we thought about Cafepress, a very popular on-demand store site that can configure easily. The problem is they were too expensive. We found our way to Tee Public and are very happy with them.
Setting it up is as easy as uploading artwork and selecting the different items you want it to appear on. It took me just a few hours to set up. We’re happy with the quality of the merch, also.
If you happen to be interested in setting up your own merch store for YOUR cause, I recommend it. In fact, you can help support our show by using the URL http://tee.pub/lic/iMZbWt-HRwU to set up your store. It’s a basic referral program.
Thanks!
