Amazon offers the Preethi Eco Twin Jar Mixer Grinder for $77 with free shipping. That's the lowest price we could find by $21. It features a 550-watt heavy-duty motor, 1.5 liter jar with detachable multi-purpose blade, 0.5 liter chutney jar with a fixed multi-purpose blade, and two flexi lids.

Update: Walmart now offers it for $73.67 when you choose in-store pickup.
