There's an Avon lady in my neighborhood who-bless her heart-is always putting catalogs in a plastic bag on my mailbox flag. Since I have a ton of Fall catalogs I was considering doing this too with a not saying call for a new catalog, blah blah. Does anyone else do this? Is it legal to mess with peoples' mailboxes? What time of day should I do it? Before the mailman makes his run or after? Thanks!
