Where are the best and most reliable places to purchase authentic comic toys, both new and vintage?

For new comic toys, reputable sources include major retailers (Target, Walmart, Amazon), dedicated online specialty stores (BigBadToyStore, Entertainment Earth, Sideshow Collectibles, AmiAmi), and local comic book shops or toy stores. For vintage or pre-owned items, look to specialized online marketplaces (eBay, Mercari, Facebook collector groups), local comic conventions, antique malls, or specialized vintage toy shops. Always research sellers, check feedback, and be wary of deals that seem too good to be true to avoid counterfeits.
