I often have diet Coke, but for both budget reasons and 'it's a pain for me to wrangle cases of it', I tend to buy a month at once and make it last out, so I am not inclined toward sharing widely.

Part of me would like to do snacks, but the rest of me is at 'that is more wrangling of logistics than I am reliably up for'. (Plus the 'trying not to limit sugar, which means having left overs kicking around after such things is a complication. I do eat some, just I'm pretty picky about what, and it mostly doesn't overlap to baked goods.)
