There are many brands available on the borofree app.
For most retail cards, you can use them either in-store or online. Please check the terms and conditions of the individual retail card for exact locations.
Simply generate a retail specific code in the borofree app and present it at the in-store checkout or enter the code online.
You can request cards from multiple retailers up to the total value of your Salary Advance limit e.g. you could request £25 from an online retailer and £50 to use at your local supermarket for food and essentials.
