Looking for window wipe refiller

Hello,

 

I'm looking for one pair of refiller (20 inch) for the window wipes of my old Honda Accord. I went to AutoZone Woburn this morning and I was told they stopped selling refiller from two months ago. They just sell blader. I think it's too expensive and waste. Does anyone know where can I found refiiler? Any suggestion is appreciated. Thank you very much.
