Like picking a favorite on-screen moment, choosing just one is a challenge.

With billions of dollars in merchandise sales, the empire of the “Star Wars” franchise is an unstoppable force. A Jedi craves not these things, but “Star Wars” fans buy them in droves. Bed sheets, lunch boxes, Lego sets, action figures, lightsabers, costumes – there is an ever-increasing number of ways for fans to express their love with “Star Wars” goods.

The rarer items fetch staggering prices on eBay and are kept in pristine, unopened condition, while others have seen more than their fair share of playtime as scenes are re-enacted by adoring fans, young and old alike.

Three local fans tell us about their favorite things in the galaxy that is “Star Wars.” For a gallery of photographs of their incredible collections, go to pressherald.com.
