# Using Promo Codes

> Received a CallTuv promo code from a campaign or email? Here's how to apply it at checkout and how discounted credit works.

**TL;DR:** Received a code from a CallTuv email or campaign? Enter it in the promo code field at web checkout - you pay the discounted price and still receive the full credit.

If we've sent you a promo code - in an email, a campaign, or a special offer - you can apply it when topping up on the web.

## Applying a code

1. Open **Balance** in the web dashboard and choose your [top-up amount](/help/8412937-how-to-top-up-your-balance).
2. Enter the code in the **Enter promo code** field. Pick a valid top-up amount first - codes apply to a specific purchase.
3. The discount is reflected at checkout before you pay. Complete the payment as usual.

You'll get the **full top-up value as calling credit** even though you paid the discounted price, and your [invoice](/help/2085461-invoices-receipts-and-vat-details) reflects what you actually paid.

## Where codes don't work

- **Mobile in-app purchases** - codes apply to web checkout only, since app-store purchases are priced by Apple/Google.
- **Expired or already-used codes** - if a code doesn't validate, it may have expired or been redeemed; the checkout will tell you.

## Removing a code

Changed your mind or mistyped? Use **Remove promo code** next to the field and enter a different one before paying.
