We spend what we can afford, sometimes €150, sometimes €70. We have a 9yo, he'd like an Xbox, he's not getting one cos we can't afford it. Maybe next year.
But we're not in the UK, so we don't do panto, FC steamtrains, FC visit, Christmas markets, ice skating etc. We have a 15yo fake tree, homemade decorations, I use fabric wraps and bags for gifts that after now in their 8th year of use, sink don't have to buy paper. I make five or six Christmas cards for family abroad.
He dies have a December birthday, too, add o that bumps up the price!
We swim on Christmas day (we're in Spain, not that warm!), have churros and hot chocolate, Christmas morning is pancakes, stockings on the bed, advent calendars, films, have family and friends over, spend a lot in really good food.
I'd say it depends on your budget, which can change yearly. I'm hoping to have a job to go back to in October, so just fingers crossed we can afford a Christmas stocking each this year.
