I've attended a few funerals recently, one was donations if desired and the other was just a floral gift or my attendance, but here the undertakers don't take a percentage for themselves, in saying that, my friend who was related to the deceased where a donation was asked for, I had decided not to put in the box as it was at the porch of the church and I didn't really like that side of town (don't trust the locals - in my minds eye I could imagine gurriers coming and nabbing the box while we are all inside) instead I go onto a website RIP.ie and there you can pay directly to the charity that the deceased would have been connected with before dying i.e Irish Cancer Society, Home Care team (Like Macmillan nurses) Heart foundation and the list goes on, I prefer give online - long answer cut short
