I had a quick question regarding coupon codes and the marketplace. I have a few different features and promotions on my website that offer coupon codes to customers to help increase sales and marketing. I realize that Sellers may not want to participate in offering these discounts, so I was wondering if there was some sort of system that would allow me to offer store-wide coupon codes that apply to every product, no matter who sells it, but I simply pay out the difference so that the Seller does not lose any money.
For example, I offer a coupon code for 5% off. A customer applies it to a Seller's item that costs $100, so they end up saving $5 and only paying $95. Rather than only adding $95 to the Seller's current balance, could we instead add all $100 (this isn't counting the commission, of course), and my business will simply cover the $5 difference so the seller still receives all of their money?
