About Walker Marketplace

Walker Marketplace, run by Betty Walker, is a go-to source for trading cards and TCGs, sports cards and memorabilia, and broader collectibles and comics. With seven years in the business, Betty has built a shop that regulars return to for consistent stock and a genuine eye for the hobby, whether buyers are chasing a specific rookie card, filling out a set, or hunting graded pieces worth adding to a collection. The range reflects real experience sourcing across categories rather than a narrow, one-note inventory. Buyers can expect straightforward listings, honest condition notes, and careful packing for cards and collectibles that need to travel safely. Betty sells across Shopify, Whatnot, and TikTok Shop, so shoppers can browse a standing storefront or catch live breaks and drops depending on where they prefer to connect. Based in Grand Rapids, Michigan, Walker Marketplace has grown alongside an active collector community, and that hands-on, relationship-driven approach shows in how orders are handled and how questions get answered. It's a shop built for people who take their collecting seriously and want a seller who does the same.
