Do I REALLY need a YOGA MAT?

Yes, yes I do, I ultimately determined, as part of my THREE-HOUR wandering through K-Mart today. Or is it Big K now? Or K & Kinda Sears? All I know is that 3 hours wasn't NEARLY long enough. There remains SO much to browse and buy! And I went in mainly for bedding...yet got none. All I know is that K-Mart is a VERY exciting place to shop...honest. Now if you'll excuse me, I have to surf the late-night net while taking in the soothing scent of Martha Stewart's Summer Beach candle...
