How McDonald's Selling System Took An Extra $1.79 Right Out Of My Pocket

"Do You Want Fries With That?"

I wasn't that hungry. I only came for a chicken sandwich.

But now I was second-guessing myself.

Do I want fries? The question seemed simple.

The answer was simpler.


How do I turn down something as delicious as fries?

I do want fries with that.

I didn't know it, but I was just upsold.

That little statement not only got me to spend $1.29, but it also got me to spend an extra $1.79.

My order total should have been $1.29.

But with the addition of the fries, my order was now $3.08.

That was a 41% order total increase!

According to, McDonald's added $28 million in additional revenue by asking if people wanted fries with their order.

McDonald's only needs a small percentage of people to say yes in order for them to make substantial increases to their bottom line.

And every time a server forgets or gets lazy and refrains from asking that question...

McDonald’s loses out, BIG time.

This same tactic is used by businesses like Amazon, Starbucks, Apple, every major airline and even BMW, to double, triple or even 10x their bottom line.

I know what you're thinking right now.

"What does any of this have to do with my business?"

The point is, they make a crapload of money by asking if their customers want to buy more products.

Every online business and online seller should be like McDonald's.


They don't have to spend more on marketing.

They don't have to spend more money on advertising.

They already have the customer at their business making a purchase and they only have to ask one simple question.

Every online business should be selling using the same upselling techniques like these massively profitable companies.

But most businesses are not...and I'm assuming you're not either.

So let me ask these two questions:

What other products can you offer your customers that will enhance their experience?

Whether it's one or a few or even if you don't have any, there is an opportunity to develop a product.

What amount of money are you leaving on the table by not offering those products after the purchasing sequence?

If you have only one product or service, just by adding more products you have the potential to drastically increase your revenue.

So let's assume you add a product with half the price with the same profit margin what would that do for your business?

What if you added more than one, what would that do for your business?

Do you see the value of a single upsell and what it can do for your business?

That's why I built Cartfuel.

So you can maximize your revenue potential.

We want to help you make more money with less work.

Cartfuel is a simple payment solution platform that allows you to sell one-time, monthly, or yearly products...

And then upsell your customers more products AFTER the initial purchase with a single click of a button.

The best part is the customer does not even have to re-enter their credit/debit card information.

Here is how it works:

1. Create a Cartfuel account.

2. Connect your account to Stripe.
3. Create your first core product followed by the product you want to upsell.
Save it.
4. Then place the Cartfuel embed scripts on your favorite web/landing page builder.
Voila! Now watch as more money comes in.

As long as your platform of choice accepts embed scripts, you can use Cartfuel to accept payments...

AND offer one-click upsells to make more money without doing anything extra.
