I totally agree with what you guys are saying about rockauto.com & their bogus shipping charges. It makes their pricing very deceptive, and I really don't care for that.
I use rockauto.com to look up part numbers from my recliner. They usually list a good variety of options/parts. I use their part numbers to shop around. If I can find a better deal @ Walmart, Auto Zone, Amazon or wherever, I buy from them instead.
These rear wiper blades for example - I started with rockauto.com, & I went from there. I can be in my recliner and see my Mirage takes a 12" rear wiper blade and Forester takes a 14" rear wiper blade. In the case of the Trico rear wiper blade, the company website confirmed it would be a factory fit for a Mirage.
Looking for a rear wiper blade that fits & having to run around from store to store would frustrate me. I've grown to love recliner shopping in recent years!
