Query: Save your Receipt

I purchased my pressure washer a couple months back. I had assumed this would be a quality product, and it did infact work well for a few months before the trigger handle started to leak causing the pressure to drop considerably. The problem was a cracked plastic washer inside the handle. The folks at Karcher were very nice and explained that had I saved the receipt I wouldn't be out the [money] for a replacement handle that I now am.
