About While Supplies Last

Get more sales for your store by displaying low inventory alerts on products, and leveraging scarcity, a powerful principle of persuasion.

Have you ever lined up outside of a big box store after a Thanksgiving meal to get that great Black Friday deal? Or camped out overnight for concert tickets? Or rushed to pre-order that hot new smartphone online at midnight?

Camping outside of a strip mall on a holiday in November just to get a discount on a TV seems a little crazy, right?

So why do we do it?

Because of scarcity. Scarcity has a profound effect on human psychology.

When we believe a product is in short supply, we want it more!

No one wants to miss out on a hot product or a great deal.

You can get more sales for your store by leveraging the powerful principle of persuasion.

While Supplies Last makes your products more attractive by showing your customers when their availability is limited.

And it all happens automatically.

Whenever your product's inventory drops below a threshold you specify, While Supplies Last automatically adds a note to the product's page stating the remaining inventory, like this:

"Only 19 left in stock - order soon. (10 are in shopping carts)"

By showing that a product may sell out soon, it creates a greater sense of urgency to buy.

The biggest online retailers are all using this same principle of scarcity to boost conversions and sell more product.

You choose the color, font size, the inventory threshold, and even the text. (Or leave it at our best practice default settings.)

Frequently Asked Questions

Q - What if my product has multiple variants? While Supplies Last will display multiple low inventory alerts on products that have multiple variants with low inventory

Q - Are there any requirements? Yes, just one: you must have inventory tracking enabled on your products. (Otherwise, how would we know when supplies are low?) It doesn't have to be on all products, just the ones that will use While Supplies Last.

If you're looking to improve your CVR by adding some "real" urgency...(none of those fake timers etc..) this is a GREAT way in doing so. FOMO! On top of a great app, the customer service is fantastic. I was having a little troubleshooting issue setting it up and Kurt was able to fix it within a couple of hours. Thanks!


Does exactly what the APP should do and amazing service if you need help. Quick response time. Highly Recommended to create urgency


Really easy to use and setup. Simple to customize with CSS. I had to contact them and got a reply super fast.

Thank you for the feedback.

The minimal plain-text of our widget is by design. Like the similar unstyled plain text shipping countdown timers used by major marketplaces like Amazon and Etsy, we're able to avoid the spammy "as seen on tv" look and ensure the widget fits in most store's designs.

Because the app is developer-friendly, it readily accepts custom CSS and can easy be styled by a theme developer or CSS-fluent merchant.

Hope that explanation of our design thinking helps.
