Unfortunately if you so create a new product or service it’ll be really hard to find you this way and it might require a lot more money and effort to reach out to the audience.
Amazon would hate this, but make a deal with shopify to speed up spidering their sites. Then, spider all other retailors.
You put in a product id/name, and it only shows results from amazon, shopify sites, and vetted retailers.
The manual curation part, is vetting the retail site. Walmart would be a problem(for example), unless it was easy to tag 'sold by walmart'. Amazon's filter would only include shipped by amazon stuff.
So like 'hanes t-shirt', and you get 7 links, from 7 sites, all woth prices and shipping cost estimates.
Amazon has horrible pricing, bordering on predatory for some things. Maybe I'll do this, I'm bored this summer.
