Question 1

Which coupon extension app is best for a Shopify store?

Accepted Answer

Pick the one that can show you what it earned. Benson is the only app here with a holdout: it leaves a share of extension sessions alone and compares them with the rest, and none of the other listings mentions one. Its Free plan also shows you the size of the problem before you pay.

Question 2

What's the difference between Veeper and KeepCart?

Accepted Answer

Veeper has no free plan, only a 14-day trial, and prices by orders: $59 a month covers 1,000, then $39 for each extra 1,000. Its listing says it works on all Shopify plans. KeepCart has a free monitoring plan, then paid plans at $49 a month flat for stores not on Plus and $99 or $199 set by orders; its setup guide says its checkout blocking needs Shopify Plus. Both offer a replacement code in place of the extension's pop-up, and neither listing mentions a holdout (checked 17 October 2026). Benson has a free plan, prices by sessions, works on every plan and measures its result against a holdout.

Question 3

Which coupon extension blockers work without Shopify Plus?

Accepted Answer

Benson's checkout code policy runs as a Shopify function in a public app, so it works on every plan. Veeper's listing says it's available on all Shopify plans, and LeakHunt's docs say it doesn't need Plus. KeepCart's setup guide says its checkout blocking works only on Plus, and Promo Pirates' listing says the same of its code blocking (checked 17 October 2026).

Question 4

What's the difference between an extension blocker and a discount code blocker?

Accepted Answer

An extension blocker acts only in sessions where a coupon extension is present, so customers without one keep the codes you sent them. A code blocker, such as Halt or Bee Keeper, turns codes off or limits them for every shopper, which also catches the customers you meant the code for. Benson, Veeper, KeepCart and LeakHunt work per session.

Question 5

What can Benson do in Shopify checkout?

Accepted Answer

Shopify doesn't let apps run code on checkout pages, so no app can hide an extension's pop-up there. Benson sets a flag on the storefront when it sees a coupon extension. At checkout, a Shopify discount function then lets only the codes you allowlist apply in those sessions. Shoppers without an extension aren't affected.

Question 6

Is cleanCART still available?

Accepted Answer

No. cleanCART's Shopify App Store listing says the app isn't currently available (checked 17 October 2026). Benson covers the same job on Shopify.

Question 7

Do I need Shopify Plus for Benson?

Accepted Answer

No. Benson's storefront embed and its checkout code policy work on every Shopify plan. The code policy runs as a function inside the Benson app, and Shopify lets stores on any plan use public apps that contain functions.
