How do you feel about this – “Flat 50% off – For 1 Hour Only!“?

Your heart races quickly, and before you could think of adding the product, the deal is gone. Well, that’s the power of a WooCommerce flash sale- it creates urgency, excitement, and a rush of customers who don’t want to miss out on a great deal.

Now if you have excess inventory, slow sales or want to capture new customers, why don’t you try flash sales?

And you can set it up within a minute. Learn how to launch WooCommerce flash sales.

But first, let’s get our basics clear.

Why run a WooCommerce flash sale?

Flash sales aren’t just about discounts-they’re strategic. Here’s some important reasons why you shouldn’t miss them:

  • Creates urgency & FOMO (Fear of missing out): Limited-time deals nudge customers to make quick decisions, which promote impulsive buying.
  • Boosts sales in a short time: Since flash sales are time-sensitive, they quickly give a boost to your revenue.
  • Attracts new customers: Flash sales can be a great way to attract new customers.
  • Clears out slow-moving inventory: Got products gathering dust? A flash sale can help you clear them out fast.
  • New product hype: If you are launching a new product, using flash sales can be a great way to motivate people to try it.

How to run a WooCommerce flash sale?

Running a WooCommerce flash sale can look complicated, but not with Smart Coupons.

Unlike WooCommerce’s basic coupons, Smart Coupons allows you to schedule discounts, apply them automatically, and show storewide notices so customers don’t miss out.

You can also create BOGO deals, gift cards, bulk discounts, and special offers-all without extra work. More sales and less hassle.

Let’s say you’re running a “Midnight Madness Sale” where customers get 20% off storewide from March 15, 12:00 AM to March 15, 01:00 AM.

Here’s how you can set it up:

  • Go to your WordPress Admin > Marketing > Coupons > Add coupon.
  • Name your coupon (MIDNIGHT20) and add a description. This description will be visible on the flash sales banner on the website.
  • Next, select Percentage discount in Discount type and enter the 20 in Coupon amount.
  • Select the expiry date and time and set it to March 15, 01:00 AM.
  • If you want, enable the ‘Auto-apply’ option, so the discount applies automatically at checkout. If not, you can show the banner with coupon code and users will need to enter that code manually.
  • Now under the Publish section, near the Calendar icon, click on the Edit link.
  • Choose March 15, 12:00 AM as the start date and time.
  • Click on Schedule.

That’s it. Your flash sale coupon is ready.

Once you are done with the coupon, you can use Smart Coupons ‘Storewide Notice‘ feature to show the flash sale coupon code storewide.

Why can’t customers resist flash sales?

Because it taps into the basic human psychology.

Let’s decode the hidden psychology behind flash sales and why customers find them irresistible:

  1. Scarcity effect: When something is available for a short time, it automatically makes the offer more desirable. When customers feel that they are missing out, they act fast.
  2. Instant gratification: The urgency of a flash sale triggers quick decision-making, making shoppers feel excited and rewarded.
  3. Competitive shopping: When people feel like having better deals than others, they try to check out faster.
  4. Loss aversion: People hate losing out more than they love gaining something. A flash sale makes them feel like they’d be losing a great deal if they don’t act now.
  5. Surprise & excitement: Flash sales break the same old routine and add an element of surprise, keeping customers engaged and coming back for more.

Conclusion

Overall, a well executed WooCommerce flash sale isn’t just about slashing prices, it’s more about creating urgency, driving engagement, and boosting sales in a short time.

Whether you’re looking to clear out inventory, attract new customers, or simply boost your revenue, a flash sale can be a game-changer for your WooCommerce store.
