Having Mail Forwarded: Suggestions?

My bank has a free online app that allows me to set up bill paying either manually or automatically. Mine is set up to pay the balance automatically and I can move money into the account on line as well. I leave it that way whether I'm on the road or not. The remaining mail is usually garbage and I have the PO hold it. They'll do that for 30 days at a time, so I ask a friend to pick up the junk once a month and save it for my return.
In return, I take care of their mail and furkids while they are out of town. And I spoil them so they won't eat dry dog food when Mom and Dad come home. ;)
