The Bottle Is $67. The Cost Is How Often You Need It.

A bottle is $67. On a daily schedule it lasts 2-3 months. That means 4-6 bottles a year. Here is the 36-month math for Pay Once and for Subscribe & Save. You choose the cadence. You keep the control.

The small number that isn't small

A small number looks friendly. It feels easy to say yes. But the real price is not the number. It is how often the number happens.

Monthly is 12 times a year. Over three years, that is 36 times. A small repeat can grow into a big spend. So we will do the arithmetic. Plain and straight.

How long a bottle lasts in real use

Each bottle is 100 ml of undiluted fine fragrance oil. No water. No alcohol. No fillers. It is made for two-fluid atomization. It makes a 2.4-micron dry mist. No water. No heat. No residue. No added humidity.

How long it lasts depends on how you run your machine.

We will translate that into yearly costs next.

The 36-month math, worked

Here are the only numbers you need:

Use profiles on a daily schedule:

Pay Once, no discount:

Pay Once, 2-bottle cart (10% off, $60.30 each):

Pay Once, 3+ bottle cart (15% off, $56.95 each):

Subscribe & Save, billed monthly:

Read that last line again. A monthly cadence will send 12 bottles a year. On a daily schedule you use 4-6. The price is not the number on the bottle. It is how often the number happens.

Two ways to save 15% — which fits which household

You have two paths to the same unit price shown above.

If you do not want three bottles at once, a 2-bottle cart gives the 10% price. Many homes buy two and are set for several months.

The honest warning about auto-charge outpacing use

Auto-charge is easy to start. It is also easy to forget. The shape of the cost is different.

If you want the lower unit price without a monthly cadence, use the 3-bottle cart. Same price per bottle as shown above. No auto-charge.

What Pay Once actually means here

This is our published policy:

Scent Plan for machines is finite: "After your final payment the plan stops. Nothing renews unless you choose it. You keep the machine."

There is one real term on machine plans only. If you cancel a Scent Plan before the final payment, the machine's retail price is billed ($100 Rover to $595 Estate XL). The machine is free only with a completed plan. This is disclosed at checkout and again at cancellation. This term does not apply to oil orders.

Practical checkout notes

Choose your cadence, keep the control

Now you have the math. Over three years, the difference is not the sticker. It is the rhythm.

Either way, you choose when the number happens. That is how you keep the cost small.
