The minimum top up is £10, so top up and then buy a £7.50 goodybag, and then go back and queue another £7.50 goodybag, thats the best thing to do in this case, just remember to turn off your mobile data to stop the airtime credit being taken before you do the above.....
£10 minimum top up I’m afraid.
But you have a couple of options which will cover your goodybags for the next few months as some of the other members have suggested.
It all depends what goodybag you were planning on purchasing. If it was £10, then the option to top up with £15 will then give you enough credit for the next 2 months worth of goodybags.
The suggestion for the minimum top up to be lowered has been suggested to Giff Gaff many times (by me also) but it has been kept at £10. Let’s hope it’s changed in the future, but I can’t see it happening 😬
