I manage the food supply side of our local trussell trust FB.
We tend to be overrun with pasta, beans, tinned fish etc but check with your local place.
We love getting treaty stuff. It does make a difference if you can treat yourself and your kids, nothing patronising about it. If you have kids of school age individually wrapped things like penguins etc are great for packed lunches. Condiments like ketchup, mayo, salt, oil etc.
Advent calendars and Easter eggs etc. Selection boxes etc. We have a central HQ which manages 6 centres/cafes that issue the food. Each is given staple items according to what they order (some are massively busy etc) plus a selection of extra bits like this. The busier centres get more. When they're gone they're gone, just how it is.
Booze either gets bought by volunteers, or put into raffles etc. We also take second hand clothes and have regular sales, we do a tombola as part of that and nice bottles of booze or whatever go in there.
Damaged/slightly out of date stuff gets put to one side, again volunteers can buy it. Soup kitchen comes to collect some of it.
Cleaning stuff. Just because you are having a tough time doesn't mean you don't want to keep a clean house, and you still need to wash up etc. So we don't ask for it specifically as it would dilute the food message but cleaning stuff is so appreciated by us and the recipients.
Toiletries, as above. Soap, shampoo, loo roll, deodorant, sanpro. All mega important
