- Step 1 Find We gather codes from merchant sites, newsletters, and affiliate feeds.
- Step 2 Test at checkout A real person enters each code at the merchant checkout to see if it applies.
- Step 3 Stamp the date Codes that work go live with the date we last confirmed them.
- Step 4 Re-check We re-test over time and remove codes that stop working.
Every discount code on The Planet Deals is tested by a real person at the merchant checkout before we publish it, and we show the date we last confirmed it. Here is exactly how that works.
The short version
We find a code, a real member of our team enters it at checkout to see if it applies, and we publish only the codes that work. Each one carries the date we last tested it, and we re-check codes over time. If a code stops working, we update it or remove it.
Step 1: How we find codes
We gather codes from merchant sites, official newsletters, brand pages, and affiliate feeds. We do not publish a code just because it appears somewhere. Finding a code is only the start.
Step 2: How we test them
A person on our team goes to the merchant, adds an eligible item to the cart, and enters the code at checkout. We watch what happens to the order total. If the discount applies, the code passes. If it is expired, regional, or tied to conditions the listing does not mention, it does not go live as a working code.
Step 3: What "last verified" means
When a code passes, we record the date and show it on the page. The last verified date tells you the most recent day we saw the code work at checkout. It is not a promise that the merchant will keep the offer live forever, because stores can change or pull a code at any time, but it does tell you how fresh our check is.
Step 4: Real shopper votes
Shoppers can tell us whether a code worked for them. These real votes help us catch a code that has quietly expired between our own checks. We never invent these numbers, and we never show a fake counter.
Step 5: When codes expire or fail
Codes do not last forever. We re-test codes over time, and when one stops working we either replace it with a current code or take it down. If a live sale beats every code, we say so, even when a code would earn us more.
What we will never do
- We never disguise a regular sale as a working code.
- We never invent savings figures, success rates, or verification counts.
- We never let an affiliate commission decide which codes we show or how we rate them.
Frequently asked questions
How do you verify a discount code?
A real person on our team enters the code at the merchant checkout and confirms the discount applies before we publish it.
Why did a code not work for me?
Codes can expire, run out, or apply only to certain items, regions, or first time customers. Check the date we last verified it, read any conditions on the page, and let us know so we can re-test it.
How often do you re-check codes?
We re-test codes over time and update the last verified date when we do. Real shopper votes also prompt us to take another look.
