Knack, PS4 – £30.21
Knack, PS4 – £30.21
First, purchase $49.99 PSN credit from Amazon US. To purchase digital goods from Amazon US, use your UK Amazon account, and add a US billing address to your account. This address needs to be a valid US address, but nothing will be sent there, and you can access all your games through their website. Some card issuers may charge a fee.
Then using a US PSN account, activate the credit, and use it to buy this.
This will leave you with $8 credit left over.

Knack is actually cheaper on Amazon’s PSN store itself rather than going through the hassle of buying PSN credit and buying it through the PSN webstore.
