Great video but...
Why your microscope are 2-3 times more expensive compare to Amazon?
I've got the SWIFT380B for 203$ Canadian (new/open box, free next day shipping) or 299$ full price (Canadian). Add 80$ Cdn to get the trinocular version.
715$cad for your comparable model (shipping include)

They may have had a good sale going on that the time that you looked at it. We include a reflected light illuminator and filter kit which make it a little pricier, but otherwise we closely match the base price of the SWIFT380T. $715CAD sounds very high to me though. Shipping may be particularly expensive to where you live in Canada. As a small business, there is no way we can compete on shipping price with amazon for remote locations. For shipping in the USA, we typically match or beat Amazon shipping prices (without prime) and speed.
