Send happy mail. Did you know you can mail a small package of candy or a small toy priority mail with stamps? If it weighs less than 13 ounces, you can put stamps and an address on it and drop it in a post office box. Look at https://www.usps.com/ to calculate how much it will cost.
I looked it up today and here are some general guidelines, although prices change frequently.
To mail a 1 ounce package just about anywhere in the United States from my address was 2.07 and to mail a 13 ounce package was 3.77 no matter what zip code I put in. Just for fun, mail someone a package of crayons, a candy bar, a book or a small toy. Make someone's day. This is great for the grandkids, but everyone is a kid at heart!
