Hermes is the Spotsavr Chrome extension. It sits in your toolbar, watches for checkout pages, pulls ranked influencer discount codes for that exact store, and applies the best one with a single click. No tab-switching. No code-hunting. Just savings.
Free · Chrome desktop only · No credit card
Every feature designed to get you the best discount with the least possible friction.
The moment you land on a checkout page, Hermes knows. No button to click, no setup. It silently detects promo code fields across thousands of stores.
Codes are sorted by verified success rate, savings amount, and recency. The best code for your cart is always at the top — not buried in a list of expired junk.
Hit Apply and Hermes finds the promo field, fills it in, and submits it automatically. Watch the discount appear without touching your keyboard.
If the promo field can't be located automatically, Hermes copies the code to your clipboard and shows a notification. Paste it yourself in one keystroke.
Full support for Shopify, WooCommerce, and BigCommerce. Best-effort support for custom checkouts. Works on virtually every major e-commerce store.
Hermes only activates on checkout pages. It never reads your passwords, card numbers, or anything on non-checkout pages. See our Data Policy.
When a new version of Hermes is available, the extension badge alerts you. One download and reload — you're on the latest version.
Hermes is completely dormant on non-checkout pages. It won't slow down your browsing, eat memory, or interfere with any other sites you visit.
Hermes is free for every Spotsavr member. Create a free account, download the extension, and start saving. No subscription required for core features.
Here's exactly what happens every time you reach a checkout with Hermes installed.
Browse any store. Hermes is completely invisible — no popups, no interruptions. It's sitting in your toolbar waiting for a checkout page to appear.
The moment a checkout page loads, Hermes identifies the promo code field and fetches the best verified codes for that exact store from the Spotsavr database — ranked by success rate.
Open the extension popup from your toolbar. You'll see all available codes for the store, ranked best first. Click Apply next to any code.
Hermes fills the promo field and submits it. The page refreshes showing your discount. If one code doesn't work, try the next — the whole process takes under 10 seconds.
Hermes is built to work across the platforms powering the stores you already love.
The old way wastes time. Hermes doesn't.
