I have done the 52 week challenge but done it backwards- 52 the first week then 51 etc... It was easier as our Summer holidays are Dec/ Jan and we spend a lot of time at the beach which is a cheap day out... rather than in Winter when we do more movies etc....I also buy a $25 gift card each week to put away and spend on food, wine, decorations etc..... In Australia many of the big stores have July sales mostly for toys but also for other items as well, in which they allow you to lay- bye items until Christmas Eve. I do a lot of shopping in these sales and pay a bit each week. They hold the items, store them and I just pick them up when ready.
