Twice a year you can convert your points to cash, credit or a donation to charity. giffgaff pay these out twice a year, in June and December. Don't worry, they’ll email you ahead of time to remind you.
Just so you know, 1 Payback point = £0.01. So 500 points = £5, and so on.
You can choose one of 3 ways to get your Payback. Reap rewards as cash , credit or donate it to charity.
giffgaff will pay you via PayPal (so you'll need an active PayPal account). This option's only available if you've earned 1,000 Payback points or more.
They’ll automatically add credit to your giffgaff account at the end of each Payback period.
Your Payback will be donated to charity, and giffgaff will match it pound for pound. Now Thats A High five. (Very nice and thoughtful of giffgaff to do that, and yourself for choosing this option and it will help many)
