Cost Per Nut Coupon Code

Active codes, how to redeem them, and the boring details.

Current active codes

We list active promo codes on our pricing page when they exist. Codes typically run during launches, holidays, and partnership periods. Outside those windows, the standard pricing is already the price most users pay — there isn't a permanent discount waiting behind a code.

If you've received a specific code from us or a partner, enter it on the checkout page. Codes are case-insensitive and don't expire mid-checkout, so you don't need to rush.

Try the trial first

Before hunting for a code, start the 3-day free trial. The trial gives you the full product, and three days is enough to know whether CPN is doing something useful for you. Coupon codes only become useful once you've decided you want to keep using it.

Codes apply to the paid plan that begins after the trial. There's only one paid plan — codes lower its price, they don't unlock different features.

How to apply a code

Go to the upgrade page. Pick a plan (monthly or annual). On the checkout screen, there's a coupon code field. Type or paste the code. Hit apply. The new total appears immediately. Hit checkout to confirm.

If a code isn't working, the most common cause is that it's expired. Codes are usually time-bound, even when we don't advertise the expiration prominently. The second most common cause is mistyping — codes are case-insensitive but typo-sensitive.

Affiliate and partner codes

If you've heard about CPN from a creator, podcast, or affiliate, they often have a unique code that gives you a discount and gives them a small kickback. Using their code costs you nothing (and usually saves you something) and supports the creator who told you about us. Win-win.

We don't currently run a general public affiliate program. If you're a creator interested in partnering, reach out at steven@astrum.software.

When codes don't make sense

If you haven't started the trial yet, codes are mostly noise. Run the 3-day free trial first. If the metric is doing something useful, you'll know inside those three days — and at that point a code becomes worth applying. Hunting for a code before trying the app is putting the cart before the horse.
