Best Buy offers two 3rd-Generation Amazon Echo Dots bundled with two TP-Link Smart WiFi Plug Minis for $70 with free shipping. (Add two of each item to your cart to see this price.) That's $40 under the best price we could find for these items purchased separately elsewhere. This current-generation Echo Dot features a new speaker design, making it 70% louder than the previous model with better sound quality.
