How long do you think is reasonable to keep on forwarding post after you've moved house?
Bought in April and for the first few months I was returning everything to sender (I asked if they wanted to leave some envelopes and I'd send mail on but they said they'd changed all their addresses).
In about October I stopped and now to be honest I just bin them.
Anyway, just had a knock at the door and it was the seller asking if they'd had any mail as they were waiting on something from HMRC.
I'm trying to not to feel guilty that I've probably binned it but I do!!
