Update: Free shipping is gone but there is a new coupon code for an extra 30% off. In cart, apply coupon code DECEMBER30 for the discount. Shipping starts at $5 and slightly increases for additional items. Thanks karmalouann
Note, free shipping now is on $50+ orders (before the coupon).
Threadless.com has a Sale in progress with Tees for $9.99 and Hoodies for $29.99. They also have some of their Hoodies on Clearance for $19.95. Shipping is free. Thanks persian_mafia
