Ye Old Shoppe

T-shirts and prints

Really, there is nothing old fashioned. Most of the merchandise is available at RedBubble.com.

The t-shirts with shipping run about \(30. That is not a great price. The reason is that these are created one at a time off of a high quality t-shirt printer instead of doing a run of a few hundred using screen printing technology. RedBubble overs a variety of items with the images which have a range of prices. I am taking ~\)4/shirt. Note that I have spent on the order of $60k over the years doing the research required to generate the content.
