Exclusively for our readers, this Smart Relief Ultimate Combo, which retails for $649.99, drops from $69 to $59 with the code BRADS-UC10 at SharkStores. Even with $0.99 in shipping fees, this is the lowest price we could find by more than $20. The kit includes the Ultimate Massager, which uses an electric current (TENS technology) produced by a device to stimulate the nerves for therapeutic purposes. It comes with 10 different massage modes and 20 different levels of strength. But it also includes slippers and ear clips, which use the same technology to stimulate the nerves in your ears and feet. There is no sales tax (except NY).
