I am trying to work through the LEGO Education platform, however am stuck at where to buy a big set of gears and similar from.
There are sets of 50pcs for $40+, which is clearly a ripoff. Or 500 pieces for $100+. Clearly I'm not willing to go broke for some plastic pieces, hence the question.
How did you obtain a good amount of... pretty much all the basic parts?
I'm not sure what your use-case is here, but LEGO Education is probably the most expensive way to simply buy parts. When you purchase from LEGO Education, you are also paying for access to a bundled classroom curriculum in addition to the parts you are buying. In essence, these shouldn't be valued in $/part, but something more like $/hour of learning experience.
If you are looking to design your own learning experiences, or you just want a pile of bricks for students to engage with, LEGO Education is likely not the best value. In this case I'd recommend buying regular sets that roughly match the part profile you are hoping for. If you are comfortable buying used parts, then I'd recommend sites like Bricklink, BrickOwl, or eBay.

Actually, even LEGO PAB (Pick A Brick) can be a good choice- https://www.lego.com/en-us/pick-and-build/pick-a-brick?query=gear&system=TECHNIC&page=2
The link is a simple search I did for Technic gears.
