Hey all!
Just got the email from Cashrewards:
Quick!! Cash Frenzy Starts Now
Cashrewards have doubled the Cashback to 10%
Not so amazing now, but score big when combining with the weekly 10-15% promotions
While app purchases might not work, there is some conjecture about using this strategy: https://www.ozbargain.com.au/node/258458#comment-3873427
Not sure how long this Cash Frenzy runs for as end date wasn't clear on email.
Enjoy!
Looks like groupon will do 5% on web and 15% on app to counteract the cashback (since app purchases do not qualify for cashback)
