Somewhere around $1,000-ish seems to be the magic threshold where their rules change and you get lost in the management void.
Also, people new to a hobby won't know that B&H, or Thomann, or Sweetwater, etc, also have great customer support like Amazon.
You can’t call Amazon and ask them what equipment you need to accomplish a task. Among many other differences…
Was only trying to improve the info you offered a bit more.
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: <not authorized to sell>, 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.
I decided to think on it for a day, and sure enough by the next day B&H had the same price. Pretty sure it was a manufacturer discount but in general I think they try to match prices.
The only problem I've had over the past year or two was with a headset that didn't work properly. I returned it via a UPS will pick up the box and slap on a shipping label option. They never did. But there was eventually a tracking number in the system anyway. UPS basically shrugged and said that the computer says it was picked up. But the refund went through anyway. I assume Amazon decided that UPS had picked it up and lost it.
