Using a code when you buy an upgrade

A code takes a percent off an upgrade you buy. Where an upgrade has a price, Have a code? sits under it. A code is never needed: every upgrade can be bought without one, and nothing is ever held back from a bill for lack of one.

How to use a code

1. Under the price, press Have a code?.
2. Type the code and press Apply. Capitals, spaces and dashes do not matter, so a code can be typed as it was written down.
3. The new price shows beside the old one, struck through, with the code and its percent in a green row. The button names the new amount.
4. Press the button to buy at that price. Nothing is paid before then, and the code is checked once more when you press it.

To take a code off before you buy, press the cross beside it.

When a code makes it free

A code that takes the whole price off says Free, with Upgrade for free on the button and No card needed under it. Pressing it upgrades the bill at once, with no card and no checkout. A free upgrade puts no line on the bill, so nobody else pays a part of it.

When a code does not work

The field turns red, a line under it says why, and the price stays as it was.

• The code is wrong, or has stopped working. Check it and try again.
• The code has been used up.
• You have used the code as many times as it allows.
• The code is for another upgrade. The line names the upgrades it works on.
• Too many tries. Wait a few minutes and try again.

Applying a code needs a connection. Offline, the field says so, as buying does.

On the bill

A bill's upgrade line is what the buyer paid for it, so a code lowers everyone's part of the line by the same percent. A code is not kept between offers: each purchase takes its own. Under Upgrades and Purchases in Settings, a purchase made with a code says how much it took off.

Worked example: half price on a receipt

Maya scans a receipt at dinner for 4 people, past her free reads. The offer says £0.25 each. She presses Have a code?, types the code from a card she was given and presses Apply. The price now reads £0.13 each, with £0.25 each struck through, and the button says Upgrade for £0.50. She presses it, pays £0.50, and the receipt is read. Everyone's part of the upgrade line is half what it would have been.
