In short

Where does it get your codes?

CouponCabin's terms say Sidekick will suggest or apply only savings already in the CouponCabin.com database, which it describes as publicly available discounts.[CouponCabin, Apr 2026] (opens the source) Its Chrome listing says it finds coupon codes and tries them for the shopper.[Chrome Web Store, Oct 2026] (opens the source)

CouponCabin has gone to court as a plaintiff over its own coupon data: in 2014 it sued Savings.com and others for scraping its offers.[Technology & Marketing Law Blog (Eric Goldman), Jun 2016] (opens the source)

How does it make money from your orders?

Its Chrome listing says CouponCabin may earn a commission when shoppers use Sidekick.[Chrome Web Store, Oct 2026] (opens the source) Its terms describe cash back as US-only, with 'Sidekick-required' offers that pay out only if the shopper uses the extension.[CouponCabin, Apr 2026] (opens the source) If it's in your affiliate program, an order where it applied a code can be credited to it under last-click attribution, whoever actually sent the shopper.

What does it do in a shopper's session?

The listing says that with a click, Sidekick applies its codes in the cart, and that it also shows up in search results when the shopper searches for a store or product.[Chrome Web Store, Oct 2026] (opens the source) The Chrome listing showed 40,000 users in October 2026.[Chrome Web Store, Oct 2026] (opens the source)

CouponCabin's terms warn shoppers that some merchants don't permit Sidekick to apply savings, and remove them before checkout.[CouponCabin, Apr 2026] (opens the source) The same terms say there may be savings Sidekick is prevented from suggesting or applying because of restrictions the merchant sets.[CouponCabin, Apr 2026] (opens the source)

What does it cost you?

Every order where it applies a code gives away the discount, and the shopper was usually already at your checkout with a full basket. If it's in your affiliate program, the same order can also pay it commission under last-click attribution, on top of the discount, whoever actually brought the shopper.

So the cost is the discount plus any commission on orders that would have happened anyway, and the codes it spreads keep working until you replace them.
