Can I use a voucher code in a retailer mobile app?

It depends on the retailer. Some codes work on both the website and app, while others are app-only, website-only or limited to a particular checkout channel.

Look for channel restrictions in the promotion terms. If the same basket is available on both channels, compare the final price and any app-specific benefits before ordering.

What should I do next?

Open the relevant retailer page, compare the available VoucherHoney listings and confirm the final price and promotion conditions on the retailer website before paying.
