A man after my own heart!  Thus said, as we get older we don't need presents.  Cliche I know, but Christmas is for the children.

Far better than buying people presents, try building up a food hamper, where you see special offers like large teabags, or buy three for the price of two.  This is very much appreciated.  One old dear we visited was able to go seven weeks before having to spend any money on food!
