From April 14th, 2020 to September 20th, 2021, 100% user give 5-star rating. for Boost Your Super chrome extension.
I have tried a few cashback extensions - this one works well.
Really easy to use. I tried it first with eBay and it notified me I can boost my super for free with each purchase. Nice. I shop online a lot, and this connects up to most of the stores i go to, so my super will be boosted in no time ;-)
The best thing since sliced bread!
