I am planning to get the EOS R5 this Black Friday, so where can I get best deals on it?
^ This. Also, check the Canon Loyalty Program. Refurbished is really the only logical route because the new holiday bundles are not as good as expected. Unfortunately, the price data shows the MSRP hasn't dropped nearly enough for a body with this many years on the sensor.
To add to the point above: Louise is right about the prices being frustratingly high. If you cant snag a refurb directly from Canon, be careful where you shop. I would suggest looking at these options for a bit more safety:
Camera price are same at most stores. The difference is the bundle with lenses and free accessories, so just check Amazon, B&H Photo Video, Adorama for best deals you think.
Check refurbished EOS R5 at Canon Direct Store. The best price for it around $2000.
