@egprentice Hmm, I definitely wouldn’t expect it to take that long. According to the website, it should ship within a week or so of ordering. Maybe you could reach out to Teespring customer support to see what’s going on?
🎉 Happy Tau Day! 🎉

June 28 is special because today there are not only one, but TWO mathematical reasons to celebrate! Today is Perfect Number Day and Tau Day! If you know what connects those concepts to today’s date, be the first to leave your explanation in the comments 🔢💬
