AmazonEnhanced

Chrome extension that de-clutters Amazon, blocks dark patterns, adds seller transparency, price history, order/wishlist export, and accessibility tools.

Features

Ads & sponsored

• Sponsored-result removal (search pages, PDP carousels, infinite scroll)
• Optional shade mode (keeps tiles visible but dimmed + outlined)
• Video-ad and Prime-upsell nag removal
• Hero banner / promo strip removal

Section declutter

13 independent toggles: Brands related, Inspired by browsing, Customers also bought, Buy it again, Climate Pledge, Editorial, From the manufacturer, Compare, Subscribe & Save default, cart upsells, homepage clutter, footer, inline padding.

Cart, checkout & dark patterns

• Auto-decline warranty / protection plan. SquareTrade/Allstate upsell: "No thanks" is selected automatically.
• Force one-time purchase. Detects pre-selected Subscribe & Save radios and switches back.
• Auto-uncheck gift-receipt, share-info, and add-on dark patterns at checkout.

Transparency & trust

• Country-of-origin badge on PDPs + cached search-tile badges.
• Reveal seller. Actual third-party seller name + link near the product title.
• Variation bait warning. Flags listings with >3× price spread across variants.
• Local price history. Sparkline of every price you've seen on that ASIN. No external API, no Keepa account.
• Review-quality scoring. Polarization, 1-star share, verified-sample ratio, volume.

Price tools

• Inline price-per-unit badges (auto $/oz, $/kg, $/ct; locale-safe EU decimal parsing)
• Suspicious-MSRP flag (>70% above actual)
• Affiliate/tracking URL stripper + /dp/ASIN canonicalization
• Extra "Sort by" options: Most reviews, Newest, Best $/unit

Tools & data portability

• Copy clean product link button on PDPs (Markdown-formatted)
• Order history export (CSV / JSON) on /your-orders pages
• Wishlist export (CSV / JSON / Markdown) on wishlist pages
• Late-delivery watcher — background alarm notifies you when a promised delivery date passes without "Delivered"
• CPU Tamer — throttles Amazon's background setIntervals when the tab is hidden

Brand & seller filters

• User-defined regex blocklist

Accessibility & safety
