How to stack coupon codes with free shipping
One code box, one code — but free shipping isn't a code. How to pair our codes with the €99 / €99 / €75 free-shipping lines.
Why codes on PeptDeals are hidden until you verify your email, what one unlock gets you (every code for 180 days), and why we email you each code you open.
On most coupon sites you click a button and a code pops up. On PeptDeals, the first time you click Get code, we ask for your email instead. This post explains why, what happens next, and what you get out of it.
That’s it. One verification, all codes, half a year.
Because codes that get scraped die young.
Shops give out codes to reach real customers. When bots copy a code and post it on hundreds of pages, the shop sees it used everywhere, by everyone, and often switches it off. That’s bad for you (the code stops working) and bad for us (the shop stops giving us good codes).
Asking for a verified email is a simple filter. Bots don’t read inboxes; people do. It keeps our partner codes alive longer — and it’s the reason our partners trust us with bigger ones, including a PeptDeals-only 30% code at Nexo Research that you won’t find on any other site.
There are two ways to verify:
We also catch common typos: if you type gmial.com, we’ll ask whether you meant gmail.com.
After you verify, we set a session cookie in your browser. For the next 180 days, every coupon on PeptDeals shows its real code straight away — no more emails, no more steps. Codes you’ve already opened stay visible on the cards, even after you reload the page.
If you switch browsers or devices, just verify again; it takes a few seconds.
Every time you unlock a coupon, we send you an email with:
Why bother? Because codes get lost. You open a tab, get distracted, close the browser — and the code is gone. With a copy in your inbox, it’s there when you actually reach the checkout, even on another device.
On the email step there’s a checkbox: Send me coupon codes and deals by email. Unsubscribe anytime. If it’s ticked, we’ll also send you new partner codes and members-only deals when they go live.
Every email has a one-click unsubscribe link. Click it and marketing emails stop immediately. You can also ask us to delete your data entirely by replying to any of our emails — see our privacy policy for exactly what we store.
The best example is our Nexo Research code: 30% off with a minimum order of €100, one use per customer, available only on PeptDeals and only after email verification. It’s the biggest code on the site — and the reason the “members-only” model exists.
Ready? Head to the coupon page, click Get code on anything, and you’ll be through in under a minute. Then put the code to work with our guide to stacking codes with free shipping.
