Send us Fan Mail This week’s Selling on Giants News and Updates examines how Amazon, TikTok, Google, DoorDash, Instacart, and the payment industry are competing to control more of the customer journey. The biggest shift in eCommerce is no longer happening only on the traditional search results page. Product discovery is moving into AI conversations, social content, delivery apps, retail media networks, and connected checkout experiences. At the same time, tariffs, marketplace compliance, global logistics, and payment consolidation are changing the economics behind every transaction. In this episode, Mr. Will covers: Tariff uncertainty and Q4 landed costs The temporary ten percent United States import surcharge is approaching its current expiration date, while new tariffs on certain Brazilian goods and additional forced-labor-related trade actions remain in development. Brands preparing Q4 purchase orders need to review country of origin, HTS classifications, customs entry dates, exclusions, and multiple landed-cost scenarios before finalizing pricing or promotional plans. Amazon account deactivation and Account Health Amazon published a new prevention and reinstatement guide covering performance metrics, intellectual property complaints, authenticity concerns, restricted products, identity verification, tax records, and INFORM Act requirements. The real operator lesson is that Account Health needs a daily owner. Sellers should organize invoices, authorization letters, compliance documents, and supplier records before Amazon requests them. Amazon expands Global Warehousing and Distribution Amazon expanded GWD into Shanghai and added support for Free on Board shipping terms. China-sourced sellers can now compare Amazon’s upstream warehousing and replenishment model against freight forwarders, overseas warehouses, third-party logistics providers, AWD, and direct-to-FBA shipping. The potential benefit is lower storage and more automated replenishment. The tradeoff is greater dependence on Amazon throughout the supply chain. Amazon Alexa creates a second product-discovery shelf New research found that many Alexa for Shopping recommendations did not appear among the corresponding top organic Amazon search results. That means sellers may soon be optimizing for two different discovery systems: traditional keyword-based search and AI-generated recommendations based on shopper intent, attributes, specifications, compatibility, and use cases. TikTok Shop tests platform-managed growth TikTok is reportedly recruiting sellers for a managed-services pilot in which the platform would oversee advertising, creator recruitment, content production, listing optimization, and creative testing. Brands approached for the program need to model the full cost, including service fees, commissions, advertising, samples, fulfillment, returns, and product margin. They should also clarify creative ownership, reporting transparency, pricing control, and creator relationships. AI-generated videos flood TikTok Shop Synthetic product demonstrations and AI avatars are creating faster content production, but also introducing new risks around inaccurate claims, weak disclosure, and loss of brand control. TikTok Shop sellers should create a formal AI affiliate-content policy and regularly review the videos generating the most traffic and sales. DoorDash becomes a Shopify sales channel Eligible Shopify merchants with physical stores can now publish products directly to DoorDash while keeping product, inventory, and order management inside Shopify. This gives local retailers another way to reach nearby customers seeking same-day or one-hour delivery, but merchants still need to account for commissions, store labor, packaging, refunds, and channel-specific pricing. Google AI Mode connects with Instacart Google AI Mode can now help shoppers build a grocery list and move selected products into an Instacart cart. Search is beginning to move from answering questions to executing shopping tasks. Product availability, attributes, imagery, retailer content, category placement, and structured data increasingly influence which products AI places into the basket. Instacart expands beyond grocery Instacart partnered with Tractor Supply to offer same-day delivery from more than twenty-four hundred locations, including pet products, livestock supplies, tools, hardware, lawn products, and outdoor merchandise. Delivery platforms are becoming broader marketplaces built around local inventory and immediate fulfillment. Stripe and Advent make a bid for PayPal Stripe and Advent International reportedly offered more than fifty-three billion dollars to acquire PayPal. The offer has not been accepted, but the potential combination highlights the growing value of merchant infrastructure, wallets, Venmo, buy now pay later, fraud prevention, checkout data, and AI-enabled payments. The bigger takeaway: Platforms increasingly want to control discovery, advertising, content, inventory, fulfillment, payments, and the customer relationship. The answer is not to chase every new channel. Serious operators need to understand who controls the customer data, who owns the creative, where the inventory sits, how the platform makes money, and whether the brand still controls its economics.
