Offering retailers and distributors a chance to order your titles straight from our marketplaces is within our long-term plans, but is not something immediately offered to publishers. However, there are a couple of decent workarounds.
Publishers do have the ability to create a special discount URL that, when clicked, inserts a product into a customer's shopping cart at a pre-determined price. (Publishers traditionally use this tool to offer a sale on a specific product.) You can use this tool to offer retailers or distributors copies of your title at a reduced price so that they can then mark it up and make a bit of profit for both of you when they sell copies.
This discount will not match the margin retailers are used to from traditional distribution, but it still gives them a chance to get some titles that are not otherwise available in the retail chain.
