I try to stay updated about any stores in my region that stock comics so I'll occasionally ask around or check the internet for any shops. Through my Googling the other day I discovered that in July of 2021 (so a bit under a year ago) a new shop had opened up known as, "Just Heroes! Comics and Collectibles." I went and checked them out yesterday. I had a great time browsing, chatting with the owners, and buying some comics! Owned by Juan Dixon, he originally had an online storefront, then expanded into an antique mall before last year when he opened the brick-and-mortar store!
The shop has a bunch of the latest action figures, statues, apparel, Funk Pops, and other cool collectibles. There is also the, "Comic Cave," which I loved digging through for a variety of great comics. When it comes to comics Dixon has an extensive selection of back-issues, keeping everything in stock from notable key issues to an ample supply of dollar bin items and everything in-between.
Found at 733 Rue St Francois in Florissant, Missouri at zip code 63031, "Just Heroes! Comics and Collectibles," is open Tuesday through Sunday and closed Mondays. They offer a 15%, "Hero Discount," to all active and retired military personnel (with a valid ID showing as such). I'd recommend visiting their store in person or buying from them online. I know I'll be back in the near future so that I can get more awesome stuff!
