Pre-ordered Webcast T-Shirts are usually shipped 2-4 weeks after the shows. 

Unfortunately, there was a delay in the production of the Sphere shirts. The shirts are now in stock with Dry Goods and all pre-orders should be fulfilled by next week (June 3-7). 

If you pre-ordered a T-Shirt with your Webcast purchase Phish Dry Goods will notify you by email when the order has been processed.
