“(discount-forward hero — rotating promotional banners with percentage-off messaging)”
When every homepage visit shows "up to 70% off" or "extra 20% off sale," the page trains visitors to buy only on promotion. The hero communicates discount, not discovery — so the visitor who wants to browse new arrivals gets the sale pitch instead of a curated entry point.
“Lead with curation, not discount: "This week's 50 — our editors' picks from 800+ brands, updated every Monday." Put the sale banner below the fold for deal-seekers.”
Curation solves the paradox-of-choice problem that 100K SKUs create. A curated entry captures the browser; the sale banner captures the bargain hunter. Serving both in sequence outperforms a discount-only hero.
