We agreed years ago that we’d do a Secret Santa for the adults in the family, so each couple just had to buy one gift, then last year we decided to drop even that, as we all have more than enough stuff. We have a set limit for each DGS, and ask their parents what they’d like - some of the boys come up with a long list that we choose from, some just want one thing. If it comes in below the limit we transfer the extra over to them.
I do fill a Christmas stocking for every adult who’s at our house on the big day - sweets, a book, etc, along with the traditional apple, orange, nuts, silver coin and sugar mouse. And always a not so traditional Christmas lottery ticket.
