Surfshark Starter is £1.96pm plus VAT for 24 months. Checkout price £56.41.
Make sure to remove any coupons as this may invalidate the TCB offer.
Edit: TCB doesn’t pay the VAT so not truly 100%, however comments suggest changing your country to Jersey on the order summary screen which removes VAT and reduces price to £47.01
