I've figured out that there are only three stamps I need to keep on hand for PaperBackSwap, really:

$0.75 + $0.84 = $1.59, which is anything under 1 pound.

For additional pounds, I can add $0.48, which is accurate for pretty much any book I'd be sending.  (After a while, the prices increase less steeply.)

I guess I could do some sort of Internet-stamp thingy, but that costs more, if only in labels for the printer...
