Currently, it is more and more difficult for retailers and ecommerce stores to engage customers with their sales promotions. Frankly, regular sales do not really impress modern shoppers anymore. But! There is a solution for any troubled business wanting to boost their revenue, bring in new customers, and reward customer loyalty as well, namely – a flash sale!
This post will explore the topic of flash sales – provide a definition of a flash sale, explain how it benefits businesses, and justify why humans are so susceptible to flash-type deals. Some examples of flash sales will be presented too, as well as tips on how to run a flash sale.
A flash sale is an effective marketing tool. It is a short term promotion carried out by an ecommerce store within a strictly limited period of time, which creates great incentives for online shoppers to become interested in their brands and finally make a purchase.
You can run a flash sale on all your products or choose a set of, for example, two or three of those and offer it at extremely low prices at a particular day of the week.
Moreover, with proper technology and marketing tools, you can target a particular customer base with your flash sales – the promotion can only concern students, members of your loyalty program, or order placed only within your business' mobile app.
Flash sales generate excitement and a sense of urgency among your potential customers. Why should they buy your products on a flash sale? Well, because you certainly offer a good discount and time is ticking so… A decision needs to be made quickly in order to claim the benefits!
Flash sales also increase social engagement through the promotion of the sale itself, which brings people’s attention to your business and causes them to interact with your brand while sharing the news of the promotion on social media.
Consequently, flash sales can serve as means to attract new customers but also to simply reward loyal customers with some extra benefits. Besides, such sales promotions might also be used as an effective marketing tool for cleaning out excess inventory to make room for new products.
According to Social Marketing Fella, flash sales e-mails cause a 35% increase in daily transaction rates among businesses, compared to an only 16% increase which is generated by regular promotion offer memos sent via email. What is more, as reported by Active Campaign, thanks to flash sales emails as much as 74% of businesses had their click-to-open rates increased.
In the end, flash sales make both businesses and customers happy and the latter, when satisfied, are likely to return and buy more – 385% more on average.
Yes, flash sales are effective – they boost the revenue of an ecommerce store as flash-deals awaken a feeling of urgency among customers and make them buy products sooner than later.
Impulse-buying is certainly something online shoppers have fallen victims of at least once. Potential consumers visit retailers' websites 'just to browse,' but then end up buying something they were definitely not planning to. Flash sales only enhance this mechanism, as the limited time imposed on the promotion combined with what seems to be a once-in-a-lifetime deal really steals any time for the human brain to ponder upon the purchase.
However, flash sales also work, because they simply make customers feel good and accomplished.
According to the research carried out by an associate professor of marketing at the University of Michigan – Scott Rick – when making a purchase of a highly-desired item, the part of the brain responsible for pleasure releases the neurotransmitter dopamine and makes clients feel joyous. That effect is only intensified when that particular item is bought on sale!
What is more, humans simply love games, and attempting to make a desirable purchase within a limited time window becomes a certain competition, which is yet another factor contributing to the popularity of flash sales – humans love winning and being rewarded. Especially if they strike a deal before the time runs out! This is why introducing promotion gamification into your marketing strategy is a must.
Amazon, one of the world's largest online retailers, has succeeded at running a flash sale every single year since 2015 when the first Prime Day took place as a way of celebrating the 20th anniversary of the company. According to Digital Ecommerce 360, only in 2022, their sales topped $12 billion for a 48-hour flash sales bonanza.

During a particular period of time, for instance 20 days as of December 2022 – 20 Days of Deals – Best Buy offers a discount on a particular item throughout a 24 hour period or until it is not in stock anymore. The promotion is valid for a different item every day and the special deal is announced right after midnight.

For eager Christmas shoppers, Apexfoot offered a quick, two-day sale offering 20% off of all the products available on their website. Need a bigger discount? There is a pop-up window offering an additional 10% on your order during the sale!


Bean Box prepared a flash sale lasting only for a day during which customers were offered 15% off the company's newest 6 Merry Mornings™ Holiday Coffee Collection. Buyers were informed about the flash promotion via email.

Extending their Cyber Monday deal, Moo offered their shoppers 25% off online orders with the promo code CYBER22 throughout an additional week only.
