Purchasing a new goodybag early is only available when you have less than 5 minutes or 5MB left in your current goodybag.
To the purchase a goodybag early:
1) Login in and go to My giffgaff
2) a message will appear under my goodybags,
3) If you are recurring your goodybag, you can decide to recur your next goodybag right now,
4) If you have a queued goodybag, you can decide to start your queued goodybag right now,
5) If you have no recurring or queued goodybag, you can select a new goodybag to start right now.
6) When you purchase a goodybag early, it erases your current goodybag and you will lose any remaining allowance, so we ask you to confirm you are really sure you want to start a new goodybag right now.
7) When you select a new goodybag or recur your goodybag early, the payment for the new goodybag is taken at this point, and a payment confirmation page is displayed.
8) Your new goodybag is active and is visible in My giffgaff.
if you start using your next goodybag early, your current goodybag as well as the goodybag allowance will be lost.
