This is where the failure of the flat buffer becomes most visible, and where the most defensible alternative lives.
Traditional retail relied on blanket pricing: applying a uniform margin strategy across every SKU regardless of its role in the consumer’s basket or its sensitivity to price signals. In a stable currency environment, blanket pricing was inefficient but survivable. In a volatile dollar environment, it is value-destroying by design. It over-protects the wrong products and under-protects the ones that actually shape how buyers perceive your brand.
Modern pricing strategy replaces the blanket with a portfolio of article roles, each governed by its own logic.
Key Value Items (KVIs) are the high-visibility anchors that shape your entire price image. Consumers do not evaluate every price in your catalog. They remember a handful and use those to judge whether you are expensive or fair. Research from Priceagent (Feb 2026) frames this precisely: the right question is not “which products are our KVIs?” but “at which prices do specific products start to influence demand and perception disproportionately?” (Priceagent, Feb 2026). During dollar volatility, KVIs must track the currency-adjusted market price. Failure here is not a margin problem. It is a trust problem that affects the entire portfolio.
This is not a theoretical concern. Pricerium’s 2025 KVI analysis found that leading retailers have abandoned the annual KVI review entirely, moving to monthly or quarterly refreshes with weekly monitoring, because “the remembered prices set changes fast with promotions, pack changes, and competitor moves” (Pricerium, 2025). McKinsey similarly found that 50 to 70% of shoppers now compare prices online before making purchases either in-store or online (Competera / McKinsey data), which means your KVI pricing is being benchmarked continuously, not at the point of sale.
Sales Drivers (SDs) are the medium-frequency items that fill the basket once a buyer is already in. These items carry higher margins than KVIs but remain subject to competitive comparison in certain channels. The strategy here is to follow market averages on list price while running temporary, data-informed promotions to trigger incremental sales, ensuring the item remains basket-filling without becoming a price-image anchor you did not intend to create.
Profit Generators (PGs) are the high-margin, lower-visibility items where consumers are structurally less price-sensitive. These are your impulse-adjacent SKUs, premium variants, and category extensions where the purchase decision is driven more by convenience, positioning, or differentiation than by price comparison. Here, according to RELEX Solutions, is where retailers deliberately “raise the costs of products with low elasticity” to offset the margin investment made in competitively pricing KVIs (RELEX Solutions, 2025). In a volatile dollar environment, PGs become the margin engine that funds disciplined KVI pricing.
The critical insight is this: no flat buffer, whether 5%, 10%, or otherwise, can replicate this logic. A buffer applied uniformly inflates your KVIs, alienating value-conscious buyers precisely where brand perception is formed, while under-recovering on your PGs where you actually had room to expand margin. It is the worst of both worlds, dressed up as risk management.
