| 10% cash back” sounds great — until you realize the maximum reward is $2 |
You're scrolling through your Chase app, checking your card balance, when a banner catches your eye:
10% cash back on eBay purchases.
Ten percent sounds meaningful. You’ve been meaning to buy a camera lens, a pair of headphones, maybe a few things sitting in your watchlist. You add the offer to your card, spend $200 on eBay, and feel reasonably confident you made a smart purchase.
Then the credit posts.
Two dollars.
Not $20. Two.
The offer worked exactly as written. But the experience still feels oddly disproportionate — because the large, attention-grabbing percentage concealed a very small maximum payout.
Welcome to the world of modern card-linked offers, where the headline number often matters far less than the cap hidden underneath it.
The Math Behind the Offer
The eBay promotion in question read:
“Earn 10% cash back on your eBay purchase, including taxes and after any discounts, with a $2 cash back maximum.”
The key phrase is the last one.
A 10% reward capped at $2 only functions as a true 10% rebate on purchases up to $20.
Spend more than that, and the effective return drops quickly:
Spend $20 → receive $2 back (10%)
Spend $50 → still receive $2 back (4%)
Spend $100 → still receive $2 back (2%)
Spend $200 → still receive $2 back (1%)
At higher purchase amounts, the offer behaves much more like a flat coupon than a percentage-based reward.
None of this is hidden exactly. The cap is disclosed in the offer details. But the design of these programs tends to emphasize the percentage first and the maximum payout second — which can create a very different impression of value.
Why Percentage Framing Works So Well
This isn’t unique to Chase. Many financial and retail promotions rely on percentage framing because percentages feel scalable.
“10% cash back” sounds dynamic. Your brain naturally assumes the reward grows with your spending.
“Get up to $2 back” feels much smaller immediately, even when the two statements describe the exact same offer.
Behavioral economists sometimes refer to this kind of presentation effect as framing: the same value appears more attractive depending on how it’s presented. Credit card issuers and merchants understand this well, and offer programs are designed accordingly.
That doesn’t make the offers deceptive in a legal sense. The terms are disclosed. But it does mean the headline number can create expectations that don’t fully match the practical value of the reward.
Why These Offers Exist
Programs like Chase Offers are primarily marketing partnerships.
Merchants pay to appear inside the bank’s rewards ecosystem in the hope of encouraging:
additional purchases,
repeat customers,
or shifts in spending behavior.
From the merchant’s perspective, a small rebate may be enough to influence where a customer shops or which card they use.
A capped offer also gives the bank and merchant predictable costs. A “10% back up to $2” promotion guarantees that no individual redemption becomes expensive, even if customers make large purchases.
For card issuers, these programs also help keep users engaged with their apps and cards. The offers encourage people to browse regularly, activate promotions, and route spending through the issuer’s network instead of a competitor’s.
The “YMMV” Problem
One aspect of Chase Offers that confuses many users is that offers are not always consistent across accounts.
The same merchant promotion may appear with:
a $2 cap on one card,
a $5 cap on another,
and a $10 cap for someone else.
Rewards communities often describe this as “YMMV” — “Your Mileage May Vary.”
Users on forums like Reddit and sites such as Doctor of Credit regularly compare wildly different versions of the same promotion across accounts. Some users receive generous caps while others receive smaller ones or no offer at all.
Banks do not publicly disclose the exact criteria behind offer targeting, but spending patterns, engagement history, merchant usage, and card type likely influence what users see.
The result is a system that feels personalized, but also somewhat opaque. Two customers holding similar cards may receive meaningfully different offers without explanation.
How Chase Compares to Other Issuers
Chase is not unusual here.
American Express Offers, Bank of America’s BankAmeriDeals, and Citi Merchant Offers all use similar structures:
targeted promotions,
varying caps,
merchant-funded rewards,
and personalized availability.
In practice, the differences tend to be in scale rather than structure.
American Express, particularly on premium cards, has historically offered some higher-value promotions with more substantial caps — especially for travel, hotels, or luxury retail. Chase and Bank of America often lean more heavily toward smaller everyday offers with lower payout ceilings.
But the core model remains similar across the industry: these programs function partly as rewards systems and partly as advertising and retention tools.
That doesn’t mean they lack value. A well-timed hotel or airline offer can save meaningful money on a purchase you already intended to make. The important thing is understanding the actual rebate amount before changing your spending behavior around it.
Why Most People Miss the Cap
The structure of these apps matters.
The percentage is usually displayed prominently:
large text,
bright graphics,
quick activation buttons.
The cap often requires tapping into a separate details screen and reading a longer sentence of terms.
Most users are not going to stop and calculate the effective reward rate before every purchase. Realistically, people browse these offers casually and make fast decisions.
That gap between headline impression and actual payout is where many of these promotions derive their marketing power.
Regulators have generally shown limited interest in percentage-with-cap formatting because the terms are technically disclosed and the rewards are genuine, even if small. But there is still a meaningful difference between something being fully transparent and something being intuitively understood.
How to Use These Offers More Effectively
The simplest rule is this:
Check the cap before you shop.
If an offer says:
“10% back up to $2,”
then mentally translate it into:“Maximum savings: $2.”
That framing makes the value much clearer immediately.
A few additional rules help:
Prioritize offers with high caps relative to your expected spending.
Avoid changing your shopping habits for trivial rewards.
Compare the effective reward rate against your card’s normal earning rate.
Treat small capped offers as bonuses, not discounts substantial enough to drive decisions.
For example, if you own another card that earns a flat 2% cash back everywhere, a capped offer can mask the fact that you may earn less overall than you would with a higher flat-rate card. Because the cap dilutes your earnings on large purchases, you might actually get a better total return by ignoring the 10% headline entirely and routing the purchase to a higher baseline card.
The most valuable offers are usually the ones tied to purchases you were already planning to make.
The Bigger Picture
Rewards cards can genuinely provide value for consumers who understand how the systems work. Millions of people save money every year through points, cash back, travel credits, and targeted promotions.
But rewards ecosystems are also carefully engineered marketing systems. The presentation of an offer matters almost as much as the value itself.
A large percentage paired with a very small cap is not necessarily dishonest. Yet it can still create an impression that feels larger than the underlying economics justify.
That’s why the most important number in many card offers is not the percentage.
It’s the maximum.
