The Amazon Big Spring Sale is underway, offering an 18% discount on the Amazon Eero 7 Dual-Band Mesh Wi-Fi 7 router. The system is being sold in multiple bundles, with the 3-pack version available for $290. The price is $140, a significant discount for the system's wide coverage area and support over 120 devices simultaneously. However, the system is light on the features, but is so effective that it can be used for everyday tasks. The deal also includes a free month of eero Plus, which adds extra features not currently available to customers.
