A recent episode of The Wirecutter Show "Don't Get Swindled On Back Friday" reminded me of this thread:
Be careful of getting stuck in the sort of Google-shopping cul-de-sac. People think that they’re doing comparison shopping when they enter something into a Google search, but in truth, it’s not as broad a selection of options as they think it is. They have incentives to send you to retailers and provide you with information that may not serve you best. They’ll show you the retailers they want you to see. They’ll show you, as a result, the prices that they want you to see.

I think Kagi Shopping could be a huge selling point. Kagi can reinforce it's messaging that Kagi works for customers because they make money from customers so Kagi will find you the best prices and the best products.
Another big selling point could be that because Kagi Shopping is biased towards customers, there could be some messaging like "you'll make your money back from the money you save on an unbiased Kagi Shopping search than what it costs you to subscribe to Kagi in a year".
Shopping search is the biggest missing feature that still has me going back to Google once in a while (even if they are biased). It's useful to narrow down all my searches to things I can purchase when I'm looking for something to purchase.
