Subscription Wizard per WeirDave

Subscription Wizard helps you find the best prices across your Amazon personal and business Subscribe & Save accounts.

Features:
- Scan Prices — Fetches real-time S&S and one-time pricing for every subscription
- Side-by-Side Comparison — See personal vs. business prices with annual savings calculated
- Bulk Subscribe — Move all subscriptions to the cheaper account in one click
- Subscribe Navigator — Step through items one at a time to selectively move individual subscriptions
- CSV Export — Export subscription lists and comparison data with price change tracking
- Privacy First — All data stays in your browser's local storage. No external servers, no tracking

How it works:
1. Scan your personal Subscribe & Save page
2. Switch to your business account and scan again
3. Switch back to personal and scan one more time for complete coverage
4. Click Compare to see every product side by side, then migrate to the better price

Scans take roughly 3 seconds per subscription to avoid Amazon rate limits.
