DealDazzle

Finding a coupon code at checkout, or a cheaper version of the thing in your cart, is what DealDazzle does for you.

DealDazzle is an AI shopping assistant delivered as a free Chrome extension that applies coupons, adds cash back, suggests alternative products and tracks prices while you browse online stores.

Installing the extension is the only setup.

After that, the savings come from whatever coupons and cash back offers exist for the store you are on, so results vary from one retailer to the next.

The alternative product suggestions are also only as good as the AI's matches, so check that a suggested item really is comparable before you switch.

As with any browser extension that watches shopping activity, privacy is a fair concern.

The site says user data is secure.

The tool costs nothing, which makes it easy to test on a few purchases and see whether it saves you anything.
