gmoylan f I buy a £20 goodybag today, will i have the current non upgraded allowance, for 1 month,
Yes you will
or will something happen to the GoodBag I purchase today, after the 26th Feb.
No, your running goodybag's allowances won't change after the 26th Feb.
I assume I just need to wait to purchase my Goodbag until 26th Feb, if I want upgraded allowance,
Yes that's right. You might want to consider buying a small goodybag to see you through from today until the 26th.
