Amazon offers two Michelin Stealth Ultra Wiper Blades for $20. (Add two blades to your cart to see this price at checkout.) Plus, Prime members bag free shipping on all orders. (Non-members can spend $35 or more to qualify for free shipping; otherwise, shipping starts around $7.) That's tied with our November mention and savings of up to $9. Discount applies to blades sold and shipped by Amazon.com only.
