Also, I’m looking to buy the corresponding iPad 9, I’ve heard Best Buy is the best for refunding electronics in the US, is that true?

Best Buy Is a very good choice, but obviously there are other companies who're also vulnerable to exploitation.

I’m assuming it would be DNA?

There's also the wrong Item received, (package compatibility) the sealed box method, and the disposed of the faulty Item method.

would an iPad just be making sure that the delivery driver doesn’t ask for a signature?

A signature Is a useless form of verification - simply fake sign the consignment.
