STAR15
Terms & Conditions from the email:
The coupon code: STAR15 provides 15% OFF all deals and products except those found in the Corporate, Fundraising and St John Categories. This discount coupon is valid until October 24 2020. Any deals with Free Shipping only apply to New Zealand Shipping addresses.
Note - this code does not give you free shipping, I'm not sure why they mention it in the T&C. It can't be used with other codes that would give free shipping e.g. FBSHIP
Check the prices against your local supermarket, both New World and Countdown in Dunedin are way cheaper than the prices on the website are.
