Hi guys,
Here's the link to the page where you can order a Polaris at a 20% discount (£487.50 in VAT):
https://robertsspaceindustries.com/promotions/rsi-polaris-presale
I don't know if this link will work for everyone or if it really is an invite-only, but if you're interested in getting one of these, give it a try, you never know.
:)
