A percentage code with no ceiling is an open tab
A percentage discount code has no ceiling of its own: 40% off costs you 40% of whatever the customer puts in the basket. Coupon Shield generates unlimited unique codes and lets you set a maximum amount any one of them can take off, so an influencer or affiliate campaign cannot cost more per order than you planned.

The arithmetic
What a cap actually does
A 40% code with a 20 USD cap, against three basket sizes. The cap does nothing on a small order and everything on a large one, which is the whole point of it.
| Order value | 40% off, uncapped | 40% off, capped at 20 USD | Effect |
|---|---|---|---|
| 50 USD | 20.00 USD | 20.00 USD | Under the cap. No change. |
| 200 USD | 80.00 USD | 20.00 USD | Cap binds. 60 USD retained. |
| 600 USD | 240.00 USD | 20.00 USD | Cap binds. 220 USD retained. |
The figures above are arithmetic on a worked example, not a claim about what any store saves. What you actually retain depends on your own basket sizes and on how the code is used.
Capabilities
What the app does
A ceiling on percentage codes
Set a maximum amount a percentage code can discount. A 40% code with a cap of 20 dollars takes 20 dollars off a 200 dollar order, not 80. The cap is what keeps one large basket from wiping out a campaign's margin.
Unlimited unique codes
Generate as many single-use or limited-use codes as a campaign needs, each one distinct, so a code that leaks can be identified and killed without retiring the whole campaign.
Codes that carry your branding
Add your own prefix or suffix to generated codes, so a code reads as yours and you can tell at a glance which campaign or partner it came from.
Built for influencer and affiliate campaigns
The case this app exists for: handing a distinct, capped code to each partner, so you can attribute redemptions and bound what any single code can cost you.

Questions
Why would I cap a percentage discount?
Because a percentage code scales with the basket. A 50% code is fine on a 40 dollar order and expensive on a 600 dollar one. A cap sets the most any single redemption can cost you, which is what makes a public or influencer code safe to hand out.
How many codes can I generate?
Unlimited, on the single paid plan.
Can I tell which partner a redemption came from?
Yes, if you give each partner their own code or prefix. That is what the branded prefix and suffix option is for.
How much does it cost?
1.99 US dollars per month, with a 1 day free trial.
Does it work outside Shopify?
No. Coupon Shield is a Shopify app and uses Shopify's own discount system.
