CARBON25 is a first-month discount code, and the honest presentation is the whole shape in the open: 25 percent off the first invoice only, one code, no stacking, and at renewal you pay list price. This page prints that shape and stops there.

What the code is

Three facts, and together they are the whole code:

• 25 percent off the first invoice, and only the first invoice.
• One code, and no stacking: nothing combines with it.
• At renewal you pay list price: after its one invoice, the code's job is done.

The first month is the only month it touches

The code applies to the first invoice and to nothing after it. When that first invoice is settled, the ongoing price is the list price of the plan: the price that was always going to apply. On Starter that reads plainly: first month at the code's rate, then 5.50 per month again. The code does not ride along into later invoices, and no second invoice carries anything from it.

How it reads

Wherever the discount shows, it reads the same way every time: first month X, then Y per month. On Starter, that reads: first month 4.13, then 5.50 per month. The 4.13 is the code doing its one-invoice job; the 5.50 is the ongoing price. The two numbers sit beside each other on purpose, so nobody has to guess what the price becomes after the first month.

Where it shows

The plans page prints the first-month line beside the list price on the plan cards: the discounted first month and the ongoing price together, in that same shape everywhere the code appears. The cards are live at the plans page , and the first-month line sits beside each card's list price exactly as described.

Why the two numbers sit together

A first-month figure that hides the price behind it reads like a trick, so ours does the opposite: both numbers print side by side, the display shape says which one is the code's one month and which one continues, and nothing about the arrangement is left for you to discover later. That is the whole reason the display form exists: it is the honest shape of a first-month price.

What this page does not do

• No end date is claimed here, and no urgency lines of any kind appear: no countdown, no rush framing, no scarcity of any kind. The code is presented as its own plain shape, and that is the whole presentation.
• No combinations: one code means one code; nothing stacks, and this page invents no combined reading of any kind.
• No checkout steps: this page explains what the code is and where it shows; how or where you would use it is not described on this page, and that silence is deliberate.

If a first-month line you see ever disagrees with this shape: open a ticket from your account with what printed, and a person checks it against the pricing records.
