Grandparents-in-law are 89 and 90. They are tricky to buy for, they have everything they need if you see what I mean. Grandad-in-law used to do a lot of gardening, so that was easy enough, but as he's getting less mobile doesn't do this so much any more. We usually get Granny-in-law something for the kitchen as she likes baking, but I'm a bit stuck for ideas this year.
Any good present ideas for the elderly? They wouldn't mind a joint present, we got them a hamper one year and that's a possibility, although I suspect Granny-in-law probably re-distributed a lot to the "old people" she visits through her church.
And yes, I've tried asking what they would like, I get "oh, you don't need to buy us anything". But they won't stop buying for us, so I think I ought to try!
