To be eligible to receive $20 cashback you must spend $100 or more in one transaction on kogan.com by 28 December 2019.
Just received this promotion SMS and email for my Citibank Signature Credit Card.
Email contains last 4 digits of my card number, so possibly targeted?
Can't find any further information on it anywhere else, but will update this post as I find out more.
Is that just credit card or are debit cards eligible?
