Choose 20% off over 15% where both apply
For eligible sitewide items that qualify for either code, WELCOME20 gives 20% off compared with 15% off from SAVE15. That makes WELCOME20 the better percentage saving for the same qualifying order.
WEMISSYOU20 and WELCOMENEWUSERS also advertise 20% off sitewide. These are separate 20% options, so there is no need to settle for SAVE15 when one of the 20% codes suits your order.
Gift codes suit specific sporting orders
Use TENNISGIFT for free tennis balls on orders over $120. For a hiking purchase, FREEBACKPACK50 offers a free hiking backpack on orders over $50. These promotions add a product to the order rather than reducing the price by a stated percentage, so they are most useful when the gift itself is something you want.
Free delivery starts above $150
Decathlon Australia offers free delivery on orders over $150. This is a separate delivery saving to factor into larger sporting-goods orders.
