Sounds like a no brainer deal really. Can't go wrong with spending just a few bucks (in currency exchange) zero bucks giving you a plan lasting over several years
Update: I paid A$109 for a 3 year plan and ShopBack initially tracked A$103.65 as the cashback (but we are told it will be updated to $109 i.e. 100% cashback as confirmed by the store rep in the comments.
Notes
Excludes taxes, fees or additional extras
Cashback is only valid for New Private Internet Access Customers
Due to currency fluctuations, discrepancies may apply to the cashback amount you receive. Please note that the purchase amount ShopBack receives is not what your bank charges you, but what Private Internet Access reports back to us in AUD.
