Oh wow, wiper blades, I bought mine at my Ford dealer. Yes, they had some coupon for money off. They weren't very expensive anyway. And yes, the exact same blades ICE and FFE.
I hate to say this, I've tested way too many wiper blades the last few years. I actually tested a couple of the Goodyear super fancy models against the Ford blades - the Goodyears were not good (one brand on the driver's side, the other on passenger). The Bosch blades were great for a few months and then went bad really fast - didn't last more than 6 months. In the end, Ford actually came out the winner for working the longest, best, and staying chatter free.
If I were buying other than Ford blades, I'd get Michelin Stealth wipers, or Valeo 600 series (that's a traditional frame wiper, not for the FFE).
Oddly, more expensive isn't necessarily better.
And thank you for reminding me, it is probably time for new blades on both cars. They are about a year old now.
