Threadless is having a clearance sale on certain designs. The clearance applies only to t-shirts (men, women and children), baby clothes and phone cases, not any of their other merchandise.
Prices are all in USD, and shipping to Australia is likely to be USD10-16.50 depending on how heavy your order is (1.5kg is a lot of t-shirts though!).
For people who don't like the effect of screen printing, Threadless uses a technique called Sublimation, which means the edges are not as defined and raised, and the colours are more muted. The cotton fabric (at least of the t-shirts) is very soft.
So postage doubles the price?
