This works for the already discounted items on sale already as well. You just need to create an account/login and the voucher amount gets deducted within the "Payment" tab. So you will not see it being deducted at the subtotal level of your shopping bag. Alternatively, walk into a store and mention the coupon code above.
Shipping looks to be $10 for standard shipping and $15 for express shipping.
Cheapest is $36 after disc. Too bad can't click and collect.
Store has the same promo?
