Well, swapping friends, I went to the post office again today and my April packages went on their way. But I did find out a little tip. If you are using an envelope with a metal clasp, it will automatically be considered a package and the package rate is about $3.50. So, take off the little clasp and, Ta-Da! 70 cents! The gal at the post office took the clasps off and all was good to go.
