Walmart offers the Arris Surfboard DOCSIS 3.1 Cable Modem
with free shipping. (Amazon
has it for the same price.) That's the lowest price we could find by $29. It features 32 download channels, 8 upload channels, two Gigabit ethernet ports, and supports the most recent cable provider speeds.
Update: The price has dropped to $159.38. Amazon has matched this price
: It's now out of stock at Walmart; however, Amazon
still offers it for $159.38
with free shipping
