Anco is having a $15 mail-in rebate on several of the blades at the moment.
You can save $15 when you buy a pair of wipers of these 5 Anco models:
That’s at least what it says on Amazon.com – but when you go to the actual redemption form it says something different.
On there it lists the discount at $15 for Contour and Profile, $10 for AeroVantage and $5 for 31-Series and Winter.
But the Anco Rear Blades are also mentioned there for $5 (any Anco blades that starts with AR in the part number is considered a rear blade). The savings on the rear blade seems to be for a single blade and with the current price of $8.99 on Amazon then it looks as if you can get a rear blade for less than $4.
