My very first post so feel free to edit or delete if I've made a mistake.
I looked at signing up to Surfshark this morning and the cashback was 60% and now it is 90% a few hours later.
This is an offer I've seen many times before.
~AU $10 for 3 years after cashback (Using code: CASHREW3Y)
Just an edit: my advice is to pay using a credit card(or debit card) and not PayPal. The price is in USD and PayPal wanted to charge me $125 but I needed up paying $100 with my debit card. Hence the $10 with 90% cashback
Thanks for posting Bazk. This is a great offer as in effect you're paying just $10* over 3 years after cashback. Note that in order to buy the 36 month $99.99 plan, you'll need to click 'Shop Offer' from this link (or the main link in the post which has since been mod edited) and select 'Buy now' which auto-applies the discount code. Terms below. Enjoy :)
