Consumers everywhere are noticing something strange.

Your favorite snack looks the same.
The price looks the same.
But somehow… the product inside feels smaller.

Welcome to the era of shrinkflation.

In this episode of Selling on Giants, we break down why products across grocery stores and marketplaces are quietly getting smaller — and why inflation is only part of the story.

The bigger shift is happening behind the scenes.

Modern retail economics — especially the rise of Amazon, eCommerce logistics, and marketplace fulfillment costs — are creating powerful incentives for brands to design smaller, lighter, and more efficient products.

What looks like shrinkflation on the shelf may actually be margin engineering driven by logistics, packaging optimization, and marketplace economics.

This episode connects the dots between consumer trends, global retail strategy, and the operational realities brands face when selling across Amazon, Walmart, Target, and other modern commerce platforms.

Along the way, we look at some real-world examples making headlines right now — from shrinking chocolate bars to evolving product packaging strategies.

Because once you understand the economics behind it, shrinkflation stops looking like a mystery… and starts looking like a system.

In this episode we cover:

• The rise of shrinkflation and why brands reduce product size instead of raising prices
• Why consumers notice price increases more than quantity changes
• The Reese’s example and how iconic products make shrinkflation visible
• Cadbury and the global chocolate shrink trend happening across Europe
• How Amazon fulfillment fees and shipping costs influence product design
• Why smaller packaging improves logistics efficiency in eCommerce
• The growing policy debate around shrinkflation transparency

Key takeaway

Products are getting smaller not only because of inflation, but because modern retail and marketplace economics reward smaller, more efficient product designs.

As eCommerce continues to reshape global retail, packaging, product sizing, and fulfillment efficiency will play an increasingly important role in how brands manage margins.

Shrinkflation may not be a temporary trend.

It may be the future of retail product design.

This week on Selling on Giants, Mr. Will breaks down several major shifts shaping eCommerce, Amazon selling, and retail strategy. From AI entering Seller Central to retail media becoming a billion-dollar business, the rules of marketplace growth are evolving fast.

The common thread across this episode is simple.
Platforms are becoming smarter, more automated, and more data-driven.

Key topics in this episode include:

Amazon Adds AI to Seller Central Analytics
Amazon is embedding generative AI directly into Seller Central to help sellers analyze sales trends, advertising performance, and inventory movement via natural-language questions. For smaller brands, this could function like having a built-in analyst. For experienced operators it speeds up pattern detection across complex data sets.

Agentic Commerce and the Rise of AI Shopping Agents
New research from McKinsey highlights the next phase of online commerce. AI systems will not only recommend products but may soon execute purchases on behalf of consumers. That means product discovery could shift from human browsing to machine-driven decision making.

Target’s Advertising Business Keeps Growing
Target generated $915 million in advertising revenue in 2025 through its Roundel media network even while retail sales remained soft. This reinforces a massive industry shift where retailers are evolving into media companies and brands increasingly pay for visibility inside retail ecosystems.

Amazon Expands Product Opportunity Explorer
A new “Saved Opportunities” feature allows sellers to track niches and product ideas directly inside Seller Central. This signals Amazon’s continued push to keep product research and demand validation inside its own platform rather than relying on third-party tools.

Tariffs, Supply Chains, and Retail Cost Pressure
Costco is proactively adjusting sourcing strategies as tariffs begin influencing global supply chains again. Brands should expect renewed pressure on margins as retailers negotiate pricing with suppliers.

Returns Continue to Drain Retail Profitability
Retailers processed roughly $706 billion in product returns in 2025. Operational gaps and omnichannel returns like buy online return in store are becoming major margin challenges across retail.

Celebrity Backed Brands Continue to Reshape CPG
Kim Kardashian has joined energy drink startup Update as a co founder as the brand launches into Walmart with a paraxanthine based formula targeting wellness focused consumers.

The Bigger Theme

The future of commerce is becoming increasingly automated and data driven.

Retailers are building media businesses.
Platforms are embedding AI into operations.
And shopping behavior itself may soon be influenced by autonomous AI agents.

For brands and marketplace operators, the companies that adapt fastest to these structural changes will have the strongest advantage.

If you sell on Amazon, operate across marketplaces, or care about the future of retail, this episode provides the operator-level perspective behind the headlines.

Amazon Tightens Capital. Ads Demand Discipline. AI Compresses Competition.

This week’s Selling on Giants episode breaks down the structural tightening happening across Amazon, retail media, AI search, and global retail infrastructure. None of these shifts are cosmetic. Each one affects capital flow, attribution control, data visibility, and long-term margin durability.

Here’s what serious operators need to understand right now:

Amazon DD+7: A Working Capital Shift, Not a Fee Increase

• Funds now release seven days after confirmed delivery
• The reserve clock starts at delivery confirmation, not shipment
• No manual overrides if Disburse on Demand is not enabled
• Cash conversion cycles quietly extend

This is not emotional. It is arithmetic. If you front inventory, freight, ads, and payroll, payout timing matters. Extended float increases working capital needs and magnifies debt cost exposure. Strong brands model this. Weak capital structure gets exposed.

Sponsored Products: Is Your Account Maintained or Just Running?

• Do you know your break-even ACOS?
• Are bids tied to Revenue Per Click math?
• Are budgets open on winners and capped on waste?
• Can your team diagnose which lever moved when ACOS shifts?

Most accounts do not fail because Amazon is “rigged.” They fail because margin math, search term hygiene, and structural clarity are missing. Discipline, not emotion, separates scalable ad accounts from expensive ones.

Meta Targets Retail Media Budgets

• Closed-loop measurement improvements
• Retail data integrations
• Direct competition for Amazon and Walmart ad dollars

This is budget warfare, not branding. Attribution is becoming the battleground. Platforms that prove incremental sales impact win allocation. Habit-based budget placement is losing power.

AI Shopping Behavior Is Changing Product Discovery

• Consumers use AI tools upstream to compare products
• Listings are being summarized before shoppers land on Amazon
• Clarity and differentiation matter more than keyword stuffing

AI compresses competition. If your PDP cannot be summarized clearly in one paragraph, positioning is weak. Structured, benefit-driven content wins.

Google’s Universal Commerce Protocol

• Standardized product data requirements
• Structured, machine-readable commerce feeds
• Data integrity over keyword tricks

SEO is shifting from content optimization to data architecture discipline. Messy feeds and incomplete attributes quietly erode visibility over time.

McKinsey Grocery Report: Growth Paradox in MENA

• Consumer confidence rising
• Premium willingness increasing
• Formal grocery growth lagging

The issue is not demand. It is execution and format relevance. Retail expansion alone does not guarantee velocity. Brands must align assortment, positioning, and innovation to how shoppers actually buy.

The Big Pattern

Capital discipline is tightening.
Ad discipline is tightening.
Data standards are tightening.
Execution tolerance is shrinking.

This is not a panic cycle. It is a precision cycle.

Strong operators model cash, margin, attribution, and velocity. Undisciplined brands feel friction first.
