DH was in charge of the donations, while I went out with DD. He was underwhelmed this year - still had LOADs left. So probably about 40 overall. Other years are loads more and there seemed to be loads around.
One neighbour had so few calling, that she sent her son around later to us offering to give away candy (so that she wouldn't eat it!) and the kids in the house (there were 9 at that stage) were delighted, while the grown ups (7) had a great laugh! (#1 normally hosts houses #2, 3 and 4 after T/Ting, for the kids to run and let off steam, while the grownups have a civilised glass of wine!).
