In the heart of Westchester, tucked between the Tiki Dog Salon and an optical store in a shopping center on Galloway Road, groups of extraordinary beings come together to share their stories of good versus evil. You'll find Superman, Batman, Wonder Woman, the Teen Titans, Spider-Man, the Incredible Hulk, Iron Man, X-Men, the Avengers, and hundreds of your favorite superheroes inside the bins of Mac's Comics & Collectibles. This comic book mecca was established in 1988 by the late collectibles guru Frank Goetz. In 2006, Goetz sold his shop to a former customer, Mike McEwen, who's combined old-school brick-and-mortar retail with 21st-century social-media marketing to create a topnotch online and traditional comic book shop. Customers visiting the store for the first time receive a free comic book from the discount bins by mentioning Mac's Facebook page, where McEwen posts daily and weekly images of new issues from DC, Marvel, Image, Dark Horse, and all the niche publishers out there. Every week, Mac's holds an online contest that rewards each winner with a $25 discount on all comic books in the back-issue bins. Even better, McEwen lets his clients fill out online pull lists that allow them to hold new issues for up to seven days and get 25 percent off. On top of all that, every first Saturday of the month, Mac's Comics pays homage to FCBD (Free Comic Book Day) by giving customers one free book from the discount bins just for stopping by. Caped crusaders, it's worth the short flight to Westchester for this superhuman experience.
