Prime Day 2025 is in the books, and the top-line number is massive—$24.1 billion in U.S. eCommerce sales. But behind the scenes? Sellers are sounding off.

In this week’s episode of Selling on Giants – eCommerce News & Updates, Mr. Will breaks down what really happened during Amazon’s biggest shopping event of the year: why some brands saw record gains, while others got buried under Retail pricing and rising CPCs. We dive into seller sentiment, AI-driven product discovery, and what the post-Prime Day “halo effect” actually means for your Q4 strategy.

But while Amazon made noise, Walmart made moves—quietly launching a six-day Deals Week, pushing grocery bundles, and slashing Walmart Plus memberships. Their strategy? Outlast Amazon and lock in loyalty. Mr. Will breaks down why this matters for CPG brands and sellers eyeing omnichannel expansion.

Target’s not sitting still either. Roundel, their retail media network, just rolled out a new AI-powered ad platform that promises easier campaign setup and closed-loop attribution. Will it challenge Amazon and Walmart Connect? It depends on your category—and your expectations.

We also cover:

• L L M S dot T X T – a new open-source file that helps ChatGPT and other AI tools discover your brand in natural language search.
• Lessons from eCommerce founders who’ve lost millions—and why owning your numbers and acting fast matters more than ever.
• eBay’s push into graded comic books and authenticated collectibles
• Tariff-driven buying behavior and what the N R F says about early spending trends in June

If you’re a brand operator or agency partner navigating Amazon, Walmart, or Target, this episode gives you the clarity and strategic takeaways to move faster and plan smarter.

Listen now. Take notes. And start treating AI visibility the way you treat ad placement—strategically.

In this week’s Selling on Giants News & Updates, Mr. Will breaks down the biggest headlines impacting eCommerce brands during Prime Week—from Amazon’s push for higher ad spend to Sam’s Club stepping up its retail media game.

We start with a curveball from OpenAI. ChatGPT is becoming a legitimate product discovery engine. Brands that optimize for structured content, schema markup, and consistent product naming are already winning free traffic. Mr. Will explains how to future-proof your SEO for the age of AI search.

Then we dive into a long-awaited FBA update. Box length limits have expanded to 36 inches. No more cutting or splitting shipments for longer SKUs. If you’ve been navigating costly repackaging issues or fulfillment inefficiencies, this one’s for you.

Over at Sam’s Club, Walmart launches MAP, a new omnichannel measurement platform giving advertisers full visibility across in store, online, and app channels. It’s a clear sign that closed loop retail media is no longer Amazon’s territory alone. Mr. Will outlines what this means for attribution hungry brands.

Meanwhile, Amazon is quietly asking brands to double their Prime Day ad budgets in exchange for premium placements and early inventory access. If you're not in the pay to play tier, you might be watching from the sidelines. Get the strategy tips you need to stay competitive even with a leaner budget.

Also in this episode:

• Prime Day Final Checklist: Deal verification, ad pacing, and team readiness
• New Compliance Rules: Approved testing labs only starting July 13
• Back to School Is Now Creator Led: What this means for brands targeting Gen Alpha households
• Bulk Spreadsheet Wins: Amazon finally lets you manage variations without Seller Support
• Vendor Central Return Penalties: What happens when your product gets the frequently returned badge
• Battery Listings Update: New safety questions go live July 28 for all vendor fulfilled SKUs

Whether you're FBA, FBM, or somewhere in between, this episode helps you sharpen your ops and stay ahead of Q3 chaos.
