Get it while it lasts! As of this writing, you only have nine hours and 31 minutes to get today's shirt, "Mega Pals," at TeeFury. It features Mega Man and Rush in the style of classic cartoons such as Mickey Mouse, and is only $10, but you won't be able to get it after today. Just click here to order yours while they last.
Update: If you missed out on the shirt yesterday, you can still get it for $13 today! You have until 9AM EST (6AM PST) to order, so click here if you missed out.
Thanks to Anthony and Jacob for the tips!
