I have my bag of change for parking machines, that I keep in the car - when it is getting pretty full and I don't need parking money, I will get a few stamps for the big supermarket and add those to my card (I aim to fill at least 1 card for the big stores shop around Christmas).
Otherwise, I have a salary sacrifice going on into the credit union through work - I put money away every paycheque for birthdays and Christmas and holiday money, so that usually covers anything I need in December.
Rudy Day today. I MAY watch a Christmassy movie tonight in bed (DH is away again!) but that's about the extent of it this month (too shattered for planning).
