has 4-Pack TP-Link Kasa Smart WiFi Plug Lite (HS103P4) on sale for $39.99. Shipping is free.
Note: Out of stock now, but you can still order for shipping in about one week, as it shows in stock "December 12". FYI, this was a +77 FP deal just a few days ago until it expired!
Another note: no, this is not a repost. The other deal from the other post was fully expired. They brought the deal back, but with an "in stock December 12, 2019" tag, hence why a new thread!
