Promo codes

What are promo codes?

Promo codes are short strings of letters and numbers that customers can apply during checkout to get a discount, free shipping, or other special offers. They’re entered in a designated field on the cart or payment page and instantly reduce the total cost.

Promo codes are a common marketing tool used to drive sales, reward loyal customers, and attract new shoppers. Businesses often share them through emails, social media, influencers, or seasonal campaigns to create urgency and boost conversions.

How do promo codes work?

When a promo code is applied:

• The shopping cart total is recalculated based on the offer
• The code may apply to specific items, categories, or order totals
• Promo codes often have expiration dates and usage limit

Why use promo codes?

• Increase conversion rates
• Boost customer acquisitions
• Clear out excess inventory
• Track marketing campaign performance

Examples of promo codes

A customer is shopping on an online clothing store and sees a banner that says:

“Get 15% off your order. Use code ‘FALL15’ at checkout”

At the payment step, they enter FALL15 in the promo code field, and the discount is applied instantly to their total.

Driftcharge Tip

Avoid overusing promo codes, use them strategically to preserve brand value while driving conversions. A/B test different offers to see what resonates most with your audience.
