I made things like fudge and truffles ( used up the year befores booze in them ) they went down well. Lots of recipes online. Also home made pickles and infused oils. If you can sew, aprons in outrageous fabrics are quick and easy to make.
The Works have a number of ideas, books, or craft kits, especially for children although adults might like some of them
Primark is a good area to hunt as well. Their home ranges are better than you would expect.
One thing helps is discretely getting the word out that money is a bit tight, anyone who doesn't understand in this day and age doesn't deserve a gift anyway.
