Having lived and breathed time- and money-saving tips for over three decades now, I thought I knew it all. I cannot fathom how many thousands of tips and tricks my readers have shared together with all I’ve discovered on my own (borne out of desperation or just plain frugality). So far, I’ve learned enough to fill three hefty published books (“Tiptionary,” “Tiptionary 2,” “Cheaper, Better, Faster”) with clever tips and DIY solutions. Could it be I’ve only scratched the surface? I think so, given what I’ve learned recently.
