Delivery price for DJI Mavic Reverse USB cable is ~32 Euro (unit price is 9 Euro), which is way more that it should cost. Why DJI cannot provide more delivery options/operators with lower prices that DHL?

Well i guess they have a contract with DHL with fixed fees for delivering items.

But i let you in on a secret,........ we live in a free and open market.
So you can shop at other places in Austria/Europe for the same item.
Isn't that great!!!!!

Same item and with a lower shipping fee.
All you have to do is go onto the internet.
For that you need a computer and an internet connection.
then you goto http://letmegooglethat.com/?q=DJI+Mavic+Reverse+USB+cable

GOOD LUCK you can do it!!!!

The thing is I want to spend DJI credit to pay for this cheap cable. And the question was why DJI doesn't sell accessories with competitive prices?

And if you do one step further you will see that no one shop has it on stock (both online and local). Way easier is to buy new smartphone
