It's time for April showers, which means it's time to freshen up your wiper blades, and Amazon will sell you a pair of Anco Transforms for $22, which is a great price for two. Just pick the ones you need using Amazon's car part finder tool, and your discount will show up at checkout automatically.
Once you have your receipt though, you might be able to mail or upload it to Anco for a $10 rebate, bringing the total cost of two blades down to $12. The fine print of the rebate says it's not valid with any other promotions, but sometimes that's just legalese that they don't really enforce. I bought a pair and submitted for the rebate, and will update this post once they accept or reject it. If it works, it'll be by far the best deal we've ever seen on wiper blades, but if it doesn't, $22 is still a great deal. [Two Anco Wiper Blades, $22. Plus $10 YMMV Mail-In Rebate]
Update: My rebate was accepted. That doesn't mean yours definitely will, but it's a really good sign.
