Here's what their site says about shipping in the FAQ - I'm guessing no shirts have actually shipped quite yet, but hopefully soon.
Where is my shirt? (Also: How long will it take to get here? How are you sending it?)
Because we want every penny to go to support Colorado Wildfires as quickly as possible, we are working on a pre-ordering system. When you ordered, your ship date was listed on our website at the top. Here's how the shipping looks now:
Batch 1 Shirts:</B> Order placed between 6/27 and 6/30 at 12:00pm MST = Ship mid-July
<H6>Batch 2 Shirts:</B> Order placed between 6/30 at 12:00pm MST to current day = Ship end of July
We're working on printing and shipping them early, so they might come sooner. They are being shipped with a tracking number which you can check out on your paypal, but they are being shipped regular old USPS mail (to keep more money going to where it needs it), so you'll understand if it's not showing up at your doorstep tomorrow. Shipping times vary, so please be patient.
If we've let you know that your shirt has shipped and you haven't received your shirt yet (and you should have), submit an order inquiry form here.
