Just reminding people of the Threadless sale with summer coming up, I love the tees from here. Also, they are now accepting Paypal, and because of this have two voucher codes that can be used:
YayPal5 to get $5 off a $30 spend
YayPal10 to get $10 off a $50 spend.
When at checkout, choose the gift option to help avoid custom and RM fees.
