Just got this email from Shopback saying We haven't seen you in a while
Just make your next purchase of $20 or more using shopback by March 19, 2020 to receive your bonus
$10 Bonus Offer Ends 7 days from email send date, at 11.59pm Sydney/Melbourne time. To qualify for one $10 bonus, place an order of $20 or more (including GST, excluding delivery fees) at any store excluding Woolworths Gift Cards via ShopBack. This offer is only valid for recipients of this email. This $10 bonus is on top of the usual cashback you earn for a transaction through ShopBack. The usual cashback will added to your account first, then the bonus at a later date. The $10 bonus will be credited to your account within 2 weeks of ordering. If your regular cashback is rejected (from returns, exchanges cancellations, using unapproved coupon codes and other T&C violations), then you will no longer be eligible for the bonus. ShopBack reserves the right to terminate this offer at any time without prior notice. ShopBack reserves the right to dishonour bonuses for members who have participated in this offer in a fraudulent manner (ie. using multiple accounts). Such members may be banned and any cashback on their accounts forfeited.
I got an email that was the same but only $5 bonus cashback.
