This just in: I’ve got a great sale running on my Retropolis Transit Authority t-shirts: through Sunday, November 29, you can get up to 25% off on an order over $25 by using the coupon code SAVE25 during checkout.
The web site does a complex and mysterious calculation on your order. When I tried it with a typical dark colored t-shirt, for example, I got a discount of over 20%.
Go forth and beshirt yourself forthwith.
(If you’re of a twistier and more achaic bent, the same sale is running at my Saga Shirts Celtic T-Shirts site)
