£16...you were done. I buy mine Mail order from a supplier in Guernsey -found some years ago on Fleabay.

£10 got me three wipers one is a 20 inch (I think). Last me at least 18 months and do a great job.

I get mine from "every lttle helps" £4 each, one 22" the other 20" and change them twice a year. Once before car goes in for service to avoid "we've changed your wiper blades scenario" Well... put them back they were new last week! My air filter is easy to change, so do that before service too, and wait for the invoice. I quite enjoy the discussions that follow!
