Amazon offers two Bosch Insight Wiper Blades for a final checkout price of $22. (Add two to your cart to see this discount.) Plus, Prime members bag free shipping. (Non-members can spend $35 or more to qualify for free shipping; otherwise, shipping starts at $6.67.) With free shipping, that's as much as $16 off list and tied with our mention from a week ago as the lowest total price we could find. Deal ends December 31.
