Earlier quoted context omitted.
I'm actually surprised people buy expensive audio/video/photo equipment on Amazon, since usually their prices aren't good on those, and their packaging is very bad. That's okay for random consumer garbage, but I wouldn't order anything high-end from them.
I presume the “their” and “them” in this comment refer to third party sellers, which could be anyone. I would rather order from the brand directly, or Home Depot or Best Buy or any other established business that does not try to pawn me off as a customer to someone else.
Some examples:
Random camera: Amazon: 2000 €, any photo dealer: 1800 €
Random high-end lens: Amazon: 2500 €, photo dealer: 2000 €
Random microphone: Amazon: 275 €, A/V distributor: 220 €
Studio microphone: Amazon: , A/V distributor: 600 €
And that's before considering that Amazon is probably going to ship more slowly (even on prime) than most other "pro" dealers, and that Amazon is probably going to throw a box in a more or less empty parcel, while someone at a proper dealer will actually bother to package the stuff correctly.
