No need for any fillers to make the total $25 for FSSS, Amazon applies FSSS condition on the pre-discount price. So you are good for free shipping with 2 blades for $20.

CHECK THE SELLER ON THE BLADES NOW!!

Since Amazon defaults to showing you the lowest cost + shipping by default, you might find a 3rd party seller slipped in. Check out this way, and you won't get the deal! I just saw this with the 24" blades.

If you wanna check the official size guide from Valeo, http://www.valeowipersusa.com/fil...tabase.pdf. Hit Ctrl+F and search for your car model. For example, for a Toyota Prius, search for Prius. Confirm with Amazon as well, because if it doesn't fit Amazon may offer to exchange for free.

From Consumer Reports, the 600 did much better than the 900 and they are cheaper for my car even taking into consideration the promo on the 900.

I can't seem to post the graphic. The number (starts with 72) is the total score. Higher is better. Then you can see the average price first for an 18 inch blade and then for a 24 inch. For my car (takes 22 inch drivers and 20 passengers side), it was $18 and change shipped for the two 600 blades total. There is no promo, they are selling them discount though. I have prime.

I was just able to order the 21" at 11:45 AM CDT 2/5/12
