This coupon will get you $1 off Trident Rice Noodle Cup 50g. Should work at all supermarkets.
Alternatively, I found the same coupon on page 45 of New Zealand Womans Weekly, July 10 edition.
I couldn't find the price at Countdown but at New World they are $1.99 which with the coupon brings it to half price. As the coupon is valid until December 31, time it out with a sale.
