Everyone was pretty happy when Thinkgeek announced it was doing economy shipping for Australian customers. Looks like it's time to rejoice once more, as the popular geek gift destination is doing free economy shipping for orders over $US40. ThinkGeek hasn't put an exact timeframe on when it'll stop doing free shipping, so you might want to dip in quickly; the site notes the following fairly simple rules:
Your cart total has to be at least $40, but can be more than that.
The shipping discount will happen automagically, and will show up on the last order screen. No need for codes.
This free shipping offer will only exist for a limited time, to be nullified at the Overlords' whim, so get in while the getting is good.
