Check your inbox. I received a TCN email titled "E.O.F.Y Sale Is Here!" for 10% off, and a promo code to apply the discount.
YMMV. Some people get 10%, others get 5% discount.
Promo code: XXXXXX - valid until 30/06/21. Limited to one use per person and up to a maximum of $500. No additional cashbacks or discount applicable with this code.
[Edit]: 1% processing fee applies, so effectively 4-9% off.
Some people have trouble applying the code to Home, here's their response:
"Thank you for your email.
We are happy to confirm that the E.O.F.Y sale applies to our HOME, ACTIVE and Cinema cards. This sale is only valid for purchases made before 30/06/2021 directly from our websites - either https://thecardnetwork.com.au/pages/the-home-card, https://thecardnetwork.com.au/pages/the-active-card, or http://cinema.gift/.
Please note that the discount code you received is limited to 1 use and there's a maximum transaction of $500.
Should you meet all this criteria but still have difficulty applying the discount code on your purchase, you can go ahead and place the order and get back to us with the discount code that you have. We will check it on our system and apply the code retroactively if the criteria is met."
