Thanks, Marvin for holding down the fort while I was running around all day yesterday.
In prep for moving, we've been getting estimates on moving our worldly goods from Florida to Colorado – eventually. Since we need the money from the sale of the house before we can buy, we don't have anywhere to live out there (aside from some imposition on the kidlets). Movers are happy to store your stuff until you're ready for it.

Since we don't know where we'll live, we don't really know which furniture will fit in a new place. Plus, the décor aspects of Florida vs. Colorado have to be considered. That which works here isn't going to look right in a mountain home. Our prospective buyers want to keep a lot of our existing furniture, which is fine with us.
But movers charge by the pound. While we're happy to ditch the bedroom set, dining room, wall units, and lots of kitchen accoutrements, parting with books is much harder. And books are heavy. I checked the USPS website, looking to see what the options were. I discovered that you can send books and other media, as long as that's all that's in the box, at a price of about 1/3 of what the movers charge per pound. Our daughter and son-in-law in Colorado said they'd be willing to store boxes of books until we find a place.
