Haven't seen this mentioned here, but like everyone else I was really frustrated having to have a required delivery signature for a simple $20 order of the new props when they could only be found at the DJI store when they were first released. I noticed today that there is now a choice at check out, "Sign Up Not Required" and "Sign Up Required" which is, I think, DJI-speak for "Signature Required" and "Signature Not Required". I don't buy from them anymore but at least they heard our bitching.
