Online shoppers struggle to find the best prices, track price changes, and locate working coupon codes across many different stores. This extension automates price comparison, shows price history trends, discovers and tests coupon codes automatically, and activates cashback rewards — all within the browser while shopping.

User browses e-commerce sites → extension detects product pages → shows price history popup (drag widget) with trend data → on checkout, auto-discovers and tests coupon codes → for supported stores, prompts cashback activation (requires login) → similar products shown alongside shopping pages → Google search results enhanced with BigGo comparison links.

Target users: Online shoppers in Asia-Pacific regions (especially Taiwan, Japan, Southeast Asia) / Deal-seekers who want automatic coupon testing and price tracking / Users who shop across multiple e-commerce platforms and want consolidated price comparison

All JS files are bundled/minified (rollup), making detailed logic inspection difficult
The background.bundle.rollup.js is a single 85KB line, limiting granular code analysis
Chrome Web Store detail page was unavailable (fetch error), so store description/rating info is missing

Monetization

No paid features detected

No evidence of paid/premium features within the extension. The heuristic-detected keywords were all false positives: 'pro' matched substrings in words like 'products', 'promotions', 'problem', 'properly', 'provide'; 'checkout' refers to e-commerce checkout pages where coupons are applied; 'purchase' appears in the context of 'after every purchase made' on shopping sites (reactivating cashback tracking). No 'premium' keyword found. No payment/billing APIs (Stripe, etc.) detected. No upgrade UI or subscription gates found. The extension is free — BigGo monetizes through affiliate cashback commissions shared with users.

Confidence: 90
Payment platform: --
Source: AI / High
Login required: Yes
Reason: The cashback activation feature requires signing into a BigGo account. Locale strings explicitly state 'Sign in and activate $word$ cashback' and 'You are not sign in BigGo Shopping Assistant yet!'. The background script manages login_status, login_info, and account_token via chrome.storage and communicates with account.biggo.com (get_loginlist.php, get_token.php, logout.php) and extension.biggo.com (logout.php). The storeIframe loads an askforlogin.php URL. However, some features (price comparison, price history, coupon display) appear functional without login, making cashback the gated feature.
