If you’re planning to purchase any Echo device during Amazon’s Black Friday Sale, you can add a TP-Link Smart Plug to your order for just $5 more. The promotion is available to anyone purchasing an Amazon Echo, Echo Dot, Echo Plus, Echo Show, or Echo Spot between now and November 27th or while supplies last. Simply add the TP-Link Smart Plug to your cart along with one of the Echo models and you’ll see a discount automatically applied at checkout that lowers the price of the plug to $5. If you’ve already ordered an Echo device but didn’t include the plug, you can probably cancel the order and place it again with the plug included. Just be sure both items are still in stock before canceling your previous order.
