But they lived 2km away which is closer than the local post office......

Would you drop it in their letter box?

I offered pick up but they obviously didnt want to do that.
But honestly the thought of standing in line at the PO with 2 screaming children 2 days before christmas when i could easily drive by and pop it intheir letter box eludes me!!!

BUt i dont want to do that in case they leave me negative feedback about postage etc etc....

what would you do?
