Mark has followed up the New York Times best-seller Buy Ketchup In May And Fly At Noon with an all-new, second edition called Buy Shoes On Wednesday And Tweet At 4:00. His latest book is packed with hundreds of additional tips that will help you save money, maximize your time, improve your health and make better career decisions.

It’s easy to see why Buy Shoes On Wednesday began generating a buzz months before it was released. Readers want to know the answers to these questions:

Which is the best month to buy a cell phone?

When is the best day of the week to take your car in for a repair?

When is the best time of day to interview for a job?

When is the best month to sign an apartment lease?

Which is the best day of the week to buy things online?



Want to know the best time of day to buy shoes? The best day of the week to eat out? The best month of the year to buy a computer or go to Disney World? Buy Ketchup In May and Fly At Noon: A Guide to the Best Time to Buy This, Do That and Go There  has the answers to these and hundreds of other timing questions.

The book, a New York Times best-seller, has been written about in magazines and newspapers around the country, and Mark has promoted the book on the Rachael Ray Show, The 700 Club and other national TV and radio shows.

Here's what the critics are saying:

"...a true money-saver's tipsheet." --

"...scads of helpful bits."
-- Chicago Tribune


Mark's second book, Your Pinkie Is More Powerful Than Your Thumb, offers surprising answers to fascinating questions that few would even think to ask, such as:

Why are hospitals so worried about neckties? 

What's the most common word used by death-row inmates during their last-words speeches? 

How many American lives are saved when gasoline costs $4 per gallon or more? 

What's more -- $3 or 300 cents?

Pinkie began attracting attention long before its March 2011 release.  Five national book clubs are offering it to their members.
