"Warning: You have selected a goodybag that will last for an entire month and cannot be ended early. You will not be able to start using another goodybag until this one expires on [DATE]. If you use your minutes/text allowance before this goodybag expires, you will need to pay standard PAYG rates until [DATE], at which point you may begin using a new goodybag. If you think you will use your entire minutes allowance in much less than a month, you are advised to purchase a goodybag with a higher allowance.
Please tick to confirm you understand the above and press the 'Confirm' button if you wish to go ahead with your purchase."
Hopefully the above speaks volumes for itself, but my idea is that the above message should be displayed when someone purchases a goodybag - if not for every goodybag purchase, at least for the first time.
Too many times do people come on here and say "help I have used my inclusive minutes, how do I end my current goodybag so that a new one starts right away."
This would prevent so many newbies from making this mistake.
