In the past few weeks I have noticed that the Greggs coffee is always out of stock no matter what time of the day or when in the week I check.
I am not sure but maybe O2 has had an influx of users recently? Has the EU roaming and also O2 Priority benefits (which is better than what it is offered by other networks caused this influx)?
Has anyone else experienced not being able to redeem this perk because I can never seem to find an available offer and it is always out of stock?
