Here's one of those freebies to sign up for just in case you want it in the future. Zappos.com typically offers free priority mail shipping on all orders, however for the next 24 hours you can upgrade your account to VIP status giving youon all orders. They ran this offer last December and since then I've ordered two or three things, all of which were on my doorstep the next morning.
Fine, I admit, I only signed up so that I can say I'm a VIP somewhere. It gives me an excuse to wear my spray-painted gold suit.
