Unless you’re a regular user of the library, here’s a little-known secret: Your local library probably has scads of “free” ebooks. Anyone in Texas can get a library card at the Houston Public Library and probably other large city libraries. The amount of info online, including ebooks and research material (old newspapers), is phenomenal.
I await other responses to your inquiry.
I did not know that Auntie Mame. I just bought a new 4GB flashcard too!
