I had already owned the CE of RIFT (Steam pre-order back before it launched.). So I grabbed the Storm Legion key from Steam, and applied it to my Trion account. They said I'd need to choose a subscription plan to even apply the code to my account, and I had already been interested in the housing they added with the expansion so I went and checked off the "One Month Recurring" option. ($14.99) At the checkout screen it showed my total as $0.00, and my receipt showed $0.00.
I checked my subscription to RIFT, and it said I have 30 days remaining, and I will be billed $14.99 at the next cycle. Checked bank account, no charge.
tl;dr - Seems I got a free month of RIFT even WITH an existing RIFT account.
