“Fondue is very scalable — great for very small businesses and very big ones. It’s a fresh way to discount that’s better for the customer experience and better for your profits.” ­- HAVN

About

HAVN is a pioneering brand dedicated to protecting everyone from EMF (like WiFi and 5G) and its long-term effects on our bodies. Their range includes everything from caps and beanies to t-shirts, underwear, hoodies, and even the “ThyWrap” for thyroid protection, all designed with their signature WaveStopper fabric. Featured in Forbes, BBC, GQ, and The New Yorker, over 60,000 customers choose HAVN because they want better health, sleep, and cognition.

Challenge

HAVN wanted to offer their customers a great deal while protecting profit margins 

Because it’s made with silver, HAVN’s EMF-blocking apparel is expensive to produce. To offer a high-quality product at competitive pricing, the brand needs to protect its margins. That’s why wanted to reduce

But they needed to do it without harming two other priorities — retention and customer experience. “We have a high rate of first-time customers, and they respond well to coupons,” they explain. “Stripping away all discounts would have been too drastic. To keep those first-time customers coming back, we needed to find a middle ground.” 

HAVN was intrigued by how CashBack could boost margins while still delighting customers. CashBack is redeemed post-purchase instead of at checkout, like a promo code. Some consumers will redeem it as store credit, while others won’t redeem it at all. That makes it less costly to merchants — and the store credit option supports HAVN’s retention goals.

“Our customers love discounts, and with Fondue, we don’t have to stop giving them great deals. We can offer store credit, build CashBack into bundles, and create new kinds of shopping experiences.”

Solution

With CashBack, great deals can benefit brands and their customers 

In 2023, the HAVN team decided to double down on CashBack and run a major test of Fondue’s performance during the 2023 Black Friday weekend. 

For past Black Friday events, HAVN had offered basic discounts of 20% or more sitewide. HAVN offered every customer 15% CashBack if they choose Visa or 18% if they choose store credit. Consumers could also unlock 20% or 25% CashBack by placing larger orders.

The results were compelling. Customers loved the new offers, and Black Friday sales surpassed expectations. The store credit option also created a ripple effect in customer retention, with many customers coming back to make second and third purchases.

And most importantly, those increased sales came with more profits. Compared to prior Black Friday sales, HAVN more than halved their average discount rate from 20% to less than 10%.

“Our customers were just as enthusiastic about CashBack as coupons. 2023 was one of our best Black Fridays — and Fondue allowed us to keep more of it as profit.”

Results

HAVN saves 52% on discounts a year — but never stopped offering incredible deals 

Since seeing the results over Black Friday, HAVN has replaced coupons with CashBack in its welcome offers, product bundles, and more. It’s also become HAVN’s go-to plan for re-engaging lapsed customers. “If someone hasn’t interacted for six months, I’d send a strong CashBack offer to re-activate them,” their team says.

That’s created impressive results:

  • 52% decrease in overall discount rate
  • 3% increase in gross profit margins 
  • 32% of CashBack offers were redeemed as store credit, driving future purchases

For HAVN, using Fondue means they don't have to choose between protecting their profits and living up to HAVN's values. “We’re here to sell products that help people but also to offer a great experience,” the team says. “Using Fondue was part of that.”

“Fondue fits into essentially all marketing flows and deals we offer. We use Fondue everywhere possible instead of coupons — we pretty much don’t offer direct discounts anymore.”
