Collectors Island is a Bodegraven-based online retailer focused on trading card games and collectible products. Its range includes Pokémon items such as booster packs, booster boxes, Elite Trainer Boxes, box sets, tins, and accessories, alongside products for Magic: The Gathering and Weiss Schwarz. The store also features selected releases, including Aetherdrift, and promotes new products and deals through its website and newsletter.

Customers can browse available items, shop sale products, and find preorder listings for upcoming releases. Collectors Island notes that changing market conditions may cause preorder orders to take longer to ship. If a product is out of stock or not yet listed, customers can contact the store by WhatsApp or email to ask about a special purchase; the retailer may be able to source items on request rather than keeping every product in stock. The website offers free shipping on orders over €250 and accepts a range of payment methods, including iDEAL, Klarna, and major cards.
