In short

The original discount extension blocker is back. Benson launched in 2022, went quiet when Shopify closed its checkout to scripts, and relaunches with a wider brief: it shows stores which coupon extensions and AI shopping agents are in their sessions, what they cost, and lets them hide, cap or replace them, with a holdout behind every change.

London, 4 October 2026. The original discount extension blocker is back. Benson first launched in 2022 to stop coupon extensions taking over online stores, and it relaunches today at trybenson.com. The new Benson shows merchants which coupon extensions and AI shopping agents are touching their checkout, what that costs them, and what they can do about it.

Its long-term aim is bigger than blocking. Benson wants coupon extensions and AI agents to play by the rules, so that merchants can work with them instead of fighting them.

Who is behind Benson?#

Benson is built by Doug Silkstone, who has spent 15 years building products and growing businesses. His career started in affiliate marketing, on the paid search team at vouchercloud, one of the UK's top three affiliate publishers. From there he could see what coupon extensions were doing to the commission that flowed through the channel.

"Internally we called it the Honey Hoover. A shopper would find a brand through a review, a comparison site or a creator. Then a pop-up at checkout would claim the last click and take the commission that was meant for the affiliates further up the funnel. The networks had little reason to push back, because every one of those orders still paid them."

Doug Silkstone, founder of Benson

The merchant paid twice: once in commission on a sale it already had, and again in the discount the extension handed out. Doug built Benson so merchants could see that happening and stop it.

Today Doug also runs his own affiliate publisher, built to show how affiliates should behave: it partners with official brands and gives them back control of how their discounts appear online. He runs WithSeismic, a product engineering studio that has worked with Groupon, The Motley Fool and Contra.

Why one founder can take this on now#

"I have the expertise, but I have the same 24 hours in the day as everyone else. Before, even when I was capable of doing all of it, I couldn't take on an idea this ambitious, because I didn't have the time to build it. Now I can hand a lot of the work to agents, spend my time on the hard problems and scaffold the rest. It's been a dream."

What happened to the original Benson?#

Early access opened on 27 August 2022. One script tag removed discount extension pop-ups from a store, across more than fifty extensions, and stopped them auto-trying codes at Shopify Plus checkouts.

Then Shopify closed the checkout to scripts. It announced the end of checkout.liquid in February 2023, and from 13 August 2024 Plus checkouts moved to a sandbox where apps can't change the page. Benson's checkout protection depended on that access. Not long after, Benson was picked up by someone else and stalled.

Why relaunch now?#

"I'm back, and I'm not taking no for an answer."

Doug Silkstone

Coupon extensions never went away. In December 2024, a public investigation into how Honey claims affiliate credit led to class actions from creators. In January 2026 Rakuten Advertising, impact.com and Awin removed Honey from their networks, and plenty of merchants started asking who was really getting paid for their sales.

The next wave is already arriving. AI shopping agents and agentic browsers read product pages, fill carts and try codes on a shopper's behalf. They sit where extensions do, between the shopper and the checkout, and they can disrupt a store's margin and attribution in the same way.

What does Benson do now?#

  • Classifies every session. Benson labels each visit by who's doing the shopping: a person, a coupon extension, an AI agent or plain automation.
  • Puts agents in view. It shows how much of your traffic is agents, how it converts and how many codes it tries, and lets you cap code attempts per visit. Detection and agent analytics are free on every plan.
  • Hides extension pop-ups by rule. Observe mode shows what would be hidden before anything changes.
  • Works with Shopify's checkout as it is now. Storefront rules and checkout controls are separate jobs, and coupon control on Shopify covers what each one can do.
  • Lets you run your own offer. Your own coupon assistant, on your site and in your colours, for a fixed monthly price instead of commission.
  • Measures every switch. Each control can run against a holdout, so the lift you see is measured, not modelled.

Benson installs with one script on Shopify and other platforms, and there's a Free plan. See pricing.

Where is Benson going?#

Benson's first goal is reach: get in front of as many e-commerce stores as possible, so every merchant can see what's in their sessions.

After that, Doug expects blocking to matter less, not more.

"Discount extensions will always exist, but they'll start to play by the rules. Benson is here to police them, and to help both sides understand the value each one brings. In an ideal world Benson wouldn't need to block anything. It would be repairing a relationship between merchants and extensions that's been damaged for years."

Doug Silkstone

He sees the same pattern starting with AI agents that shop on people's behalf. A store can't always tell whether there's a person behind a session, a person with an extension, or a bot buying for someone.

"Merchants are going to have to decide how they deal with agent traffic. Do they expose more data? Change what's on the page? Give agents clearer instructions? That's conversion rate optimisation for bots, and it's going to matter as much as it does for people."

Doug Silkstone

Benson's roadmap follows that path: detect who's shopping, set the rules for extensions and agents, then help stores convert the agent traffic they want.

Who is Benson looking to partner with?#

Benson wants to work with anyone who cares about margin and what's happening on their store:

  • Performance agencies running paid and affiliate budgets for e-commerce clients. See Benson for agencies.
  • Affiliate agencies that want commission to land with the partner who earned it.
  • E-commerce brands that want to be sure they're not being taken for a ride. See Benson for e-commerce.
  • Coupon extensions and AI agent builders that want to work with merchants on fair terms.
