The offers we can never link, and the exact clause that stops us.

Every deal site is paid the same way. You click a referral link, you open an account, the site collects a commission. On the guides listed below there is no such link here, and there never will be, because each program's own terms say a link posted on a site like this one is a breach, and in almost every case the person who loses the money is the reader, not the publisher.

The six below are the bluntest cases, and the ones readers most often arrive here holding a code for. We read the terms behind all 118 offers on this site again on July 27, 2026: 39 programs forbid a page like this one from posting their link, and 18 more issue no postable link at all, because the code is minted for a single visitor or arrives inside a personal email. That is 57 of 118. If you got here because a code you found somewhere else was refused at checkout, why referral codes from deal sites do not work sorts that failure into its three causes.

The six, and the clause behind each

Venmo: publishing the link is what voids it

The reward dies at the moment a published link is used. There is a second reason to be careful with Venmo: the document governing the program is scoped to referrals completed by the end of 2024 while the FAQ still advertises an amount. The full Venmo guide lays out both problems.

Bitrefill: the terms name our whole category

Most programs restrict public posting in general language. Bitrefill describes exactly what a site like this one does, and backs it with a review step: allocation of the bonus is conditioned on a check for compliance with those terms, and misuse means exclusion and removal of bonuses from all accounts involved. The Bitrefill guide covers what the program actually pays and what spending does not count toward it.

Greenlight: the only rule that punishes both people

Greenlight's terms are the harshest in this set, because the consequence is shared, and a reward already paid can be reclaimed months later, after the subscription has started billing. Bulk emailing and distributing to strangers are grounds for immediate termination and further legal action. What Greenlight does permit is a person sharing their link with people they know, including on their own social media profile. The Greenlight guide has the current promotion window and the monthly fee that sits underneath it.

Upside: banned from exactly where people look

Very few referral terms forbid the code from appearing in the precise places people search for it. Upside's do, and social sharing is permitted only if you have fewer than 2,500 followers and stay out of public discussion forums or groups. So the answer to "where do I find an Upside referral code" is a person: a friend, a neighbour, whoever is filling up next to you. Details of what the boost is actually worth are in the Upside guide.

US Mobile: private sharing only, in those words

US Mobile's referral terms say referral links are for private sharing only, that posting them on public forums, websites, discount sites, or social media groups for mass referrals is strictly prohibited, and that the program is not intended for businesses or influencers. Three separate phrases, all pointing the same way.

Because the reward here only lands after six billing cycles in good standing, a link that was never compliant is a particularly expensive thing to discover late. Ask a friend or family member already on US Mobile to send you theirs directly. The US Mobile guide walks through the port-in requirement and the qualifying spend.

TopCashback: allowed, and deliberately not worth it

TopCashback does not ban a commercial referral, it prices it out: no more than $5 per referral through commercial means, against $40 for a personal referrer once the new member has earned their first $10 in cash back. Companies attempting to work around the policy can be cut off immediately. If you know someone who already uses TopCashback, that $40 should be theirs. The TopCashback guide explains the bar you actually have to clear, which is earning $10, not spending it.

• A personal referrer’s link, once the new member has earned their first $10 in cash back$40
• The same referral earned through commercial means, including comparison websites$5

Both figures are TopCashback's own. The only thing that changes between them is who posted the link.

Two more where the link has to arrive privately

• PayPal. Its Invite Friends terms say a referral link must not be published or distributed in public locations where the audience is likely to include people who are not your family or personal friends, and PayPal may disqualify a referrer and their referees and void all rewards. See the PayPal guide.
• DoorDash. The referral terms require the link to arrive through email, text, or the Share Your Link option, and separately revoke the credit if the referrer posted the referral link on a publicly accessible website. DoorDash also publishes no reward amount at all. See the DoorDash guide.

Three quieter versions of the same rule

Sometimes the restriction decides eligibility silently, and nothing looks wrong until the payout does not appear.

• M1. New users who sign up via affiliate links are not eligible for the referral bonus, and M1's marketing affiliates may not use referral links or receive referral payouts. A commercial link would actively cost a reader the bonus, which is why the M1 guide sends you to a friend instead.
• Varo. Varo's referral terms treat posting referral links on third-party social media, blogs, or similar websites as grounds for terminating eligibility. That is one reason the Varo guide carries no link, alongside the fact that Varo publishes no fixed amount.
• Ledger and CoinTracker. Ledger's affiliate terms bar links on couponing or cashback sites, and CoinTracker's real terms sit with a third-party network that bans deal and coupon sites and paid ads. These do not affect a reader's reward, but they do decide whether we could ever be paid for the Ledger guide or the CoinTracker guide.

A separate shape is easy to mistake for these: programs that place no restriction on where the link travels and simply pay the person signing up nothing, which on fifteen of the 118 offers here is what the terms say in as many words. Those are listed in the programs that pay the sharer only, each with the sentence that gives it away.

So how do you actually get one?

1. Ask a person, not a page. Every program here authorises exactly one channel: a link sent directly by someone who already uses the product.
2. Ask for a freshly created link where a clock is attached to it. Venmo's qualifying window runs from the creation of the referral link, so an old link can be most of the way through its clock before you ever see it.
3. Read the amount in your own app before you commit. Several of these programs personalise the figure, and the screen in front of you outranks anything a website tells you, including this one.
4. Treat a published code as a warning about the site. A page handing out an invite link for one of these programs either has not read the terms or has decided that the reader carrying the risk is an acceptable trade.

What a code on a coupon site actually is

Usually one of three things: a real person's link that someone scraped and republished, which quietly breaks that person's eligibility; a dead code from a program that has changed or ended, which has its own page here; or a commercial link earning a fraction of what a personal one would. The honest version of this business is to tell you when the best link is one we cannot give you, and then get out of the way.
