What Are White Label Coupon Extensions?

Not all discount code extensions are made directly by the company offering them. Sometimes, extensions are developed by one company but rebranded and marketed by another company as their own product. 

Essentially, the original developer creates a fully functional and customizable extension, which can be branded with a different company’s logo, colors, and other branding elements. This allows companies to offer their users a coupon browser extension service without developing the technology from scratch.


Tip: Whether a promo code extension is created in-house or via white labeling does not change how consumers use it. White labeling can be a useful strategy for the coupon business, but it makes no difference to the end user – unless the implementation quality isn’t up to par.
