I'm in Canada as well. Best prices I've found were Newegg and sometimes Amazon although I've only bought 10 & 12tb Ironwolf Pro's.
Normally around the $280 mark when they had deals. Lately I've went to WD PRO's because of the lower prices. Positive thing is they seem to run cooler.
I'm at 170tb's of raw storage and 95% full I just don't have money to upgrade anymore.
Neweggs prices have always seemed to be weird from my experience. Sometimes they make no sense at all. You'll have the same product in two different places on the website both sold by Newegg at different price points as well as the multiple sellers.
I moved back in April to a much smaller place. I am having a hard time parting with over 2500 Blurays and 4k's. On top of that thousands more of "collector" Steelbooks and custom sets from places like Nova, FilmArena, HDZeta, Manta Lab etc.
I used to have a spare bedroom dedicated to movie stuff with all my media on Billy Bookshelves and special editions and movie parapharnelia shelved and on display. Now it's all in boxes.
I have it all ripped 1:1 on my Media server plus backups but can't get myself to rid of the physical media.
