Your local outlet may or may not do this deal. This deal is randomly announced, usually ending around 2.30pm or 3pm. Guessing the start time would be noon. Was told by Nike staff they are advised by a higher up when to start running the promo.
Deal is: Buy three items get 40% off. This is discounted off each item, not the total bill, so no double discounting. Example deal: Two Nike Football track pants @ $30 each + Last season running Jacket @$60 = $120 rrp, with the discount is $72.
There is also the Catch of the day tracksuit deal: Here should be $58 posted using the 20% code on Catch's eBay.
