As part of this deal you can get 25% off your order if you use Klarna (similar to Afterpay) and that makes these four Ryzen CPUs down to some of the lowest prices they've been. Postage appears to be $15 nationwide.
For customers to be eligible to have the 4th and final payment waived the first, second and third instalments must have been paid in full and on time. Order will show the full price through the entirety of checkout, you will receive an email afterwards saying "We've got your final payment covered"
If it were me I'd be jumping on the 5950X and 5900X as they're priced really low for a lot of power, however they're likely overkill for most people and the 5800X/5600X is more than enough for gaming.
Note: Credit check will be made.
