Just a bit of info for people selling (or buying) books on the board-my PO advised if we are sending books (not mags), request the "book rate"-it is less. He said if you have (like I was sending) one or two quilting books, soft cover, about 100 or so pages each, and it will fit into a plain manilla envelope, it will cost less than a flat rate envelope. I have two books going out in one envelope at $2.83 and one going out at $2.48. He says if they are magazines, they contain advertising, so you don't get the same rate as the book rate. It is good to know to keep postage down when sending books-not to just assume the flat-rate $4.95 is cheaper!
