Welcome to the dark side.
Just a heads up, the drone you purchased isn't being fulfilled by Amazon. The seller, "GD Sales", is taking care of the fulfillment. You'll still be covered by Amazon's A-to-z Guarantee if anything doesn't go as expected, so you're fully protected. The downside is the return and refund process will take longer.
I bought from Aero Tech at the same time you did, while Aero Tech was still in the Buy Box, being fulfilled by Amazon, and not from the replacement seller GD Sales I posted the screenshot of, at a ridiculous $2149, made to look
almost exactly like "fulfilled by Amazon" but didn't say it. Amazon now says my "box of rocks" has shipped, for delivery on October 27. Clearly not in any U.S. warehouse of Amazon's! Does Amazon have a warehouse in, and an underground railroad from China now?
As to A to Z "Guarantee,", Amazon only acts as the arbitrator, and always takes the seller's side. Seller gets to pretend they never received your return, or that you damaged the item, and is free to also charge any restocking fees that they disclosed in the fine print under their own well-hidden return policy, referenced under the Amazon Return Policy as an A to Z Guarantee with a separate link to it. It's far from a Guarantee, and just proving the seller never sent the item can require waiting 3 weeks. These sellers are slimy, and will immediately "ship" from China by creating a bogus USPS shipping label, that mysteriously never gets scanned by USPS, but Amazon says that is normal, and wait for it to be scanned!
If "fulfillment by Amazon" while buying from a crooked 3rd party seller avoids going through A to Z, as you have represented, my "box of rocks" refund should be seamless! Similarly, if Amazon doesn't deliver my "box of rocks" on October 27, an immediate refund better be available. If it truly is a brand new, sealed in the box, functioning Mini 5 Pro Plus Combo with the RC 2 for $1159, then that's just an unexpected bonus! Not a believer in miracles, but I'm relying upon your superior insider knowledge here, rather than my own personal past experience and complete distrust of Amazon and their enabling of these shyster 3rd party sellers on the Amazon Marketplace.
Cheers!
