Ask hosts for a favorable price. I got so many discounts this way. You never know before asking. A button will appear on top of each listing both on list and map views. Then a popup will ask you how much you want to ask per night. You can also skip specifying an amount. Then, the plugin will open a tab and send a message to the host directly. From the plugin popup window, you can choose to not send a message automatically, in that case you would need to send the auto-generated message on the new tab. This way I got many discounts from the hosts, hope that helps you travel cheaper.
