72 Hour Sport Sales up to 75% off on shoes, clothing, equipment, nutrition.
Also from what I see, when you use the link as part of Click Frenzy you are asked to signup to the Slash Sales newsletter, they will send you a mystery code that will give you additional percentage off at the checkout. I haven't used it, but supposedly you find out at checkout.
If you don't use the click frenzy link by going directly to the website, then if you sign up you get $10 off your first order.
EDIT: Please note, for the promo code discount, as found by someone, "Your product subtotal must be at least AU$100.00 to use this promo code."
I just got some Asics trail shoes for $99 (marked down from $200) with free ship - pretty happy with that and sign up to newsletter for $10 promo code which comes imediately
