I received mail from ShopBack (to my email address, not my physical address that I stupidly recorded on ShopBack) saying there is a $2 bonus when using the ShopBack browser extension.
EDIT: Make sure you have received the email from ShopBack before installing the toolbar, otherwise you aren't entitled to the bonus.
Some T&C's below
• Offer only valid for recipients of this email who install and make a purchase using the ShopBack Browser Extension.
• To qualify for $2 Bonus Cashback, you must ‘Activate Cashback’ at any participating store through the ShopBack browser and make a transaction through that store between 12am and 11.59pm AEDT (inclusive) on 4 November 2020.
• Transaction must be $5 minimum spend including GST but excluding delivery and other fees.
• Maximum one bonus per person, regardless of the amount of purchases made through the extension.
• Participating stores are stores in which ShopBack offers cashback for, and an “Activate Cashback” prompt appears when you access the store’s website.
• The $2 bonus is in addition to the usual cashback you’ll receive for transacting at a participating store, and will not appear straight away.
• The $2 bonus will be credited as Pending into your ShopBack account by 28th February 2021 11.59PM AEDT.
• At least $10 confirmed Cashback from general purchases must be earned in order to withdraw the $2 Cashback Bonus.
• Standard store terms and conditions apply. Any violation of the terms and conditions will void your eligibility for the bonus. This includes but is not limited to purchasing items excluded from cashback, using unapproved coupons, returning/exchanging/cancelling orders.
• ShopBack reserves the right to dishonour cashback 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.
Just be sure to uninstall afterwards.
