Buy one, get one free!
Through the end of the month, we're offering free t-shirts!
For everyone one you buy, you get one free. All you have to do is add a second shirt to your cart and use coupon code "MYFREESHIRT". That's it. Works for any multiple of two shirts.
The obvious "buy one, get one of equal or lesser value...", "purchase must be made on the website", etc. stuff applies. You do need to pay for shipping on the second shirt... unless we're in the midst of one of the "Free Shipping" offers you can jump onto with your order...
...but Hey!
It's a free shirt!
