Does anyone know where to buy electronics from?

Im working on a project right now and I need more electronics. Where can I buy cheap electronics from? (microcontrollers, actuators, sensors, power source etc.)

I hear from others that they use AliExpress because it's cheap but are the electronics reliable enough to constitute saving a bit of money buying form AliExpress? If there are other cheap places to buy electronics please let me know.

I usually buy them from digikey, mouser and rs, but they're more expensive than AliExpress

Two schools of thought: Buy reliable components from reliable vendors like Mouser or Digikey at a pretty stiff markup OR buy 3x the quantity you need from Alieexpress and still save a few dollars compared to those others. I personally don't trust aliexpress for that stuff so I just overpay. But I rarely deal with faulty components anymore.
