For the most part our family has decided to not get gifts this year. We just spend time together, eat something nice and enjoy each other, except for the one child in our family that of course still gets something.
For my wifes side of the family, we decided to do secret santa this year and cap ourselfs at 30.- CHF for value.
Byo food in this case? Lest this causes more than one person to bring potato salad, lol.
Best tip for this is to designate types of foods instead of asking what they'll bring to avoid back and forth. Eg. Someone'll make the salad, someone'll make a pastry, someone'll make dessert, etc.
