How we check codes

What this means for you

• You can see how fresh every offer is

  Each one carries the date of its latest sighting or check, and says which kind it was, so you can judge it in a second.

• "Verified" is earned

  It appears only after a recorded check at the store's checkout, or a confirmation from the store or its affiliate network.

• People and scripts both check

  Our editor checks codes by hand at the store's checkout, and our own scripts try codes in real carts, re-read offers and drop the ones we can't confirm again. Each label says which kind of check stands behind it.

• The numbers are real

  Store facts come from the store's own pages, and a saving we've seen applied in a cart is labelled that way. You won't find star ratings, "used 250 times" counters or "100% working" promises here, because we can't back them up.

• Codes are meant for everyone

  We list codes anyone can use, and leave out codes that look tied to one customer, such as birthday codes, account numbers and one-time strings.

• Stale offers leave

  An offer we haven't seen again within 30 days drops off the page.

Every store page is edited by Danica P., our editor, and reviewed by Ivan P., our founder. The wider rules for our content are in the editorial policy.

Where offers come from

• The store's own website

  A site banner, a promotions or sale page, a sign-up offer, or a program page (student, military, rewards).

• Store newsletters and emails

  Welcome codes and the promotions stores send to subscribers.

• The store's social accounts

  Public codes and sales posted on its own Instagram, Facebook, X or TikTok.

• Affiliate network feeds

  Under Offertium's own publisher accounts, such as Awin and Impact, once a store's program has approved us.

• Exclusive codes

  Issued to Offertium by a store or a network.

• Codes shoppers send in

  Listed only after a check.

• Other public promotions

  Codes and sales a store has made public elsewhere, listed under the same rules and checks as everything else.

Codes that look personal or single-use (birthday codes, account or order numbers, long generated strings) are never listed. When a store's affiliate program limits which codes may be published, its rules apply.

What each label means

The labels you'll see on an offer, from the strongest evidence to the weakest:

1. Verified {date}

   A recorded check backs it: the code worked at the store's checkout within the last 14 days, or the network or the store confirmed it within the last 30 days. After that the offer shows its source label again.

2. Checked {date}

   The code worked in a real cart at the store on that date: the store accepted it and took the discount off. No purchase was made. It isn't the same as Verified, which an editor confirms at checkout by hand (see cart checks).

3. Seen on {store}'s site · {date}

   We read the offer on the store's own site on that date. It hasn't necessarily been tried at checkout yet.

4. From {network} · updated {date}

   The offer came from the affiliate network's feed; the date is the feed's own last update.

5. Last seen {date}

   A code we haven't tried ourselves yet, dated by when we last saw it published. Treat it as worth a try rather than a sure thing. Once it works in our cart check, the label changes to "Checked {date}".

Top offer

The offer that comes first under our ordering rules (see the affiliate disclosure). Nobody pays for it.

Last checked {date}

The date and method of the latest recorded check.

Offertium exclusive

A code issued to Offertium by the store or its program.

Worked for {n} shoppers

Shoppers who answered "Yes" to "Did it work?" in the last 30 days, shown once at least 5 shoppers have answered.

All dates are calendar dates: no "2 hours ago", and never a date in the future.

How a code gets checked

1. Products go in a fresh cart

   Logged out, a new cart for every code.

2. The code goes in the promo field

   Exactly as a shopper would type it.

3. We record the result

   Whether the store applied it, and what it took off.

4. And stop there

   Never checkout, payment or an account. The check identifies itself to the store.

Codes tied to one person and single-use codes are never tried. A code that worked shows "Checked {date}" for up to 60 days. If we later see it on the store's own site, that newer date is shown instead.

How long an offer stays listed

An offer read on a store's site or received from a feed stays listed for 30 days from the date on its label; a "Last seen" code stays up to 60 days. If we don't see it again in that time, it leaves the list, and it comes back with a new date when we find it again. When shoppers report a code as failing (three or more reports in seven days, with at least 60% saying it failed), it moves to the bottom of the list.

How we count our cart-test figures

On a store page, the "Cart tests" line ("34 codes checked last 30 days, 97% worked") counts every code we tried in a real cart at that store in the last 30 days. Each code counts once, by its latest test, so a code we re-check every day doesn't lift the figure, and a code that failed and left the page still counts against it. Tests our cart couldn't finish (for example, a product was out of stock) aren't counted. Codes the store took only with conditions count as worked. A store shows the figure only once we've tried at least 10 of its codes in that time.

In an offer's details, "Worked in 3 of 3 cart tries since Oct 20" counts every test of that code in the last 90 days, from 2 tests. "Worked with conditions" means the store took the code but only for certain products or above a minimum spend; it's named next to the count. Cart tests never make a code "Verified": that label stays for a check at checkout by our editor.
