I've had lots of fun during lockdown with similar initiatives and/or local places:
I took part in a book swap at Christmas with a complete stranger (got involved via Twitter) was sent a great book plus chocolates; am currently involved in a Secret Valentine (like Santa but in February via a local craft group that I belong to online); today I took some plants - babies of my house plants - to a local deli and takeaway to donate them because the owner sells a small selection of plants as well as food - she insisted that I take cake in exchange! No contest there.
Then when I was walking home I returned a book to the library which is currently only open for 'click and collect'. A staff member was at the door but no one else around. I greeted him and said Drat, I forgot to do click and collect this week ; and he replied No problem, I've put a selection of books in the window if you walk along and point I shall bring it to you. Made my day. 
I post something (a card, a letter, a gift, sweets) to my grandson every week, he is 6, and I get a video message in return.
