Is this the going price for solar filter material?

I should have done this before the eclipse, but after using welding glass and not getting that great of an image I want to look at making a proper solar filter for my telephoto lens so I can take more solar photography. Venus transit etc could be neat to get. Looking at this:

Is $66 really what this stuff goes for is that gouging? I'm willing to pay that if it's really the going rate but just want to double check that I'm not being ripped off as it seems kinda pricy.

Open to other options too. Basically I just want to be able to safely point my camera at the sun without killing the sensor. This is not for looking through with eyes (I think this is safe for that, which probably makes it more expensive) so if there is a cheaper material that will accomplish the same thing then I'm open to suggestions.

These come in different filter sizes.

That bhphotovideo site looks interesting and they seem to sell/ship to Canada. Might have to check that out.

My intention was to basically make my own filter with the film anyway. What I find odd is how the premade filters are cheaper than the film itself. I was going to make a filter that fits directly on my telephoto but it's kinda hard to justify when the premade is cheaper.

Seems kind of high. I paid $24 USD for this 5" x 5" sheet a couple weeks before the eclipse.
