Neat idea and I hope you will be successful. On initial inspection it seems like your matching algo or something is off. First example I clicked on is this dining set, which sounded like a great deal: https://www.spoken.io/page/11DmKO6MxLYnRP0tRls8 for $680. But when I click through it's actually $688 and only includes the table (is not a set as originally claimed): https://www.theclassyhome.com/Product/JFN-1511-82/Jofran+Fur...
Same with the higher price linked on your site. It's still only the table and it's out of stock. https://www.afastores.com/jofran-cannon-valley-trestle-dinin...
I think it's less frustrating browsing sites directly because their prices and stock indicators are more accurate. I get this with google shopping results, too, where you click through and either the price was totally wrong or the item is out of stock.
