I do that too. I also do it for Dell as much as I can. Sometimes if Im delivering 50 to one stop, I give up on it!
Anyone know if they actually do get billed for it? I somehow doubt it (for the big ones anyhow), or it would be fixed.
the address correction in the board does bill them and it also helps them to get the address correct in the future or they pay that fee until they do on my route so i am guessing the sig required would bill them too
