Frequently Asked Questions (FAQ)
Coupon extensions are browser extensions that buyers can install in their web browsers (ex. Google Chrome) that allow them to discover and automatically apply coupons in shopping carts on ecommerce websites.
Extensions identify and catalog coupons in three ways:
- They scrape them from the code of an ecommerce site when an extension's user manually types the code in at checkout.
- Users can directly submit coupon codes to the extension so they can be shared with other uses, and
- Some merchants may choose to partner with the extension and create coupons specifically for them.
Let's use Capital One Shopping, as an example.
With Capital One Shopping, you can shop online and save in seconds. When added to a browser, here's how the lightweight extension works:
- Instantly searches for available coupons and automatically applies them to your shopping cart. Available coupon codes are automatically applied to your cart at checkout.
- Snag exclusive rewards when you shop at stores you love. Earn Capital One Shopping rewards while you shop, then redeem those rewards for gift cards. Cha-ching!
- Compare prices on Amazon to other popular retailers. Capital One Shopping searches for a better price while you shop at Target, Best Buy and more. You'll see a friendly little pop-up if a better offer is found, including tax and shipping details.
Coupon extensions, and the platforms that participate in them, have two main purposes:
- Profit: Browser coupon extensions profit by charging commissions to participating retailers or affiliates. However, buyers on merchant and retailer sites can use Capital One Shopping, Honey or other coupon extensions to find codes whether or not the merchant has elected to "participate."
- Long-Term Reward Programs: Most coupon extensions offer loyalty rewards for repeat use that they eventually can monetize.
All coupon extension companies recommended on our site take security very seriously.
You can also set how much information you wish to share with some of the coupon extensions. Just keep in mind that some of the information is needed for the extension to actually work.
If you think that your personal data is not secure with any of the coupon extension companies recommended on our site, or you don't feel comfortable sharing it, you can always uninstall the app. The process is very easy, and you can do it at any time.
