The holidays are here — don’t miss the chance to create Christmas Promotions your subscribers can redeem *right in checkout*.

Turn “maybe later” into “I’m in.”

With Promotions in COS Business Engine, you can run real, trackable campaigns across your fiber footprint—welcome offers, seasonal deals, and bundles—without messy workarounds. Customers enter a code in the marketplace (or hit a link that pre-fills it), see the price update instantly, and complete the order with confidence. You get results you can measure.

## Why it works

- Fewer drop-offs – The discount shows up right where the decision happens.
- Smarter campaigns – Share links that prefill a code and deep-link straight to the offer.
- Real numbers – Track which promos move orders and where to double down.
- Full control – Keep offers tidy and consistent across teams and partners.

## Great use cases

- New customer promotions (first-month free)
- refer-a-friend
- weekend flash sales or holiday campaigns
- bundle nudges
- or neighborhood challenges with a unique code per fiberhood
