How It Works

Four simple steps to maximise your rewards and stretch your budget further.

  1. 💳
    Step 1

    Add your cards

    Link your UK credit or debit cards. We never store card numbers — only reward rates so we can calculate the best stack.

  2. 🔍
    Step 2

    Search merchants

    Find where you shop. See which cashback portals and voucher options apply so you know what you can stack.

  3. 🛒
    Step 3

    Enter basket size

    Tell us how much you plan to spend. We use this to work out your total yield and the best payment stack for that amount.

  4. 📈
    Step 4

    Get your stack

    We show the best card + portal + voucher combination and an explainable total yield % so you know exactly what you'll earn.
