Hmm-it seems to vary by part. What I need is 54.95 at the dot com place I linked. It is 87.98 at your place! But disposable filter bags are a lot more at the place I found. Thanks for your link. The place I found didn't have pictures on it so I wasn't sure if I was looking at the right part. Your link has all the pictures and numbers on it so I can see exactly what I'm looking at and make an accurate comparison.
