Phia is a Chrome extension that answers a simple question as you shop: am I about to overpay? Click the "Should I Buy This?" button while viewing a product and Phia compares that item against real-time listings across retail and secondhand marketplaces, then shows cheaper options without taking you off the page. Its database covers hundreds of millions of secondhand items and more than a hundred resale partners, including large platforms like The RealReal, eBay and Poshmark. Beyond price matching, it tracks saved items and reports when prices drop, and surfaces resale-value context so you can judge whether a purchase holds up over time.

Click "Should I Buy This?" on any product page and Phia checks the item against real-time retail and secondhand listings without requiring a search of your own.
If the item you are viewing looks overpriced, Phia surfaces lower-priced options directly on the same page so you can compare without losing your place.
Access deals from 150+ resale platforms, including large marketplaces such as The RealReal, eBay and Poshmark, backed by a database of 250 million-plus secondhand items.
Save products you are considering and Phia notifies you when their price falls, so you can time the purchase instead of paying full price.

SeekShop is a free Chrome extension that collects reviews from Reddit, YouTube, retailer pages, and expert sources, weights them into a single SmartScore, and explains what actually matters on the product page — then surfaces coupon codes at checkout.
Instead of trusting one retailer's star rating, SeekShop reads Reddit threads, YouTube videos, retailer reviews, and expert write-ups, then weights them into a single score.
You get a rating plus an explanation of what keeps coming up across sources, so you can see the recurring strengths and complaints rather than just a number.
Coupon codes appear on the product page and again at checkout on supported stores, saving you a separate search before you pay.
Works on Amazon, Target, Walmart, Best Buy, and 1,000+ other retailers, with no tab switching or copy-pasting product links.
