Please provide proof that I am wrong, tranquility. Thank you.
Please provide the proof you are right. When one makes an astonishing claim, one should be able to back it up with astonishing evidence. We know the common law comes up with a completely different result. Also, the UCC is not as you say regarding acceptance. Your rely upon the federal statute.
There, as in all statutes, the reasons and the history are important to understanding. See:

There you will find the statute is to prevent consumer fraud of the type I already mentioned. Where a seller intentionally places a burden on another in order to make a sale. It has nothing to do with mistakes. You may also search for the statute in federal cases to find it deals with the practices of a seller as a policy. (Also, if it gives a private right of action and/or what constitutes merchandise. [Credit card offer? Money?]) Find me the case saying loser weeps when something is sent in error.
Dell: "Sorry, but we did not have an 8GB RAM module so we installed a 16GB instead, no charge."
quincy: "That is unordered merchandise as it differs from the specs. I shall treat it as a gift under 39 USC �3009 and cancel my credit card payment.
quincy: "I ordered a pound of coffee. When it got here there was actually 1.001 pounds."
Mailorder coffee seller: "Yes sir, we put a little more in to make sure we get you a full pound."
quincy: "I requested a pound. I shall treat it as a gift."
I was going to give more to deal with each specific objection that an unreasonable person might bring up, but won't.
I am disappointed you give the OP the risk of losing a lawsuit and have a judgment against him because of what you feel unsolicited merchandise means when you are usually the first to tell a person to see an attorney when there is risk. A mistake on the part of the seller is not merchandise mailed (We have not established "mailing" as yet either.) without the prior expressed request or consent of the recipient. Sure, if the company routinely does such an upgrade and demands payment or does other acts to indicate it should be covered by fraud statutes, it certainly could be. That is why the FTC writes:
Q. What should I do if the unordered merchandise I received was the result of an honest shipping error?
A. Write the seller and offer to return the merchandise, provided the seller pays for postage and handling. Give the seller a specific and reasonable amount of time (say 30 days) to pick up the merchandise or arrange to have it returned at no expense to you. Tell the seller that you reserve the right to keep the merchandise or dispose of it after the specified time has passed.
The reason to do this is, if the seller does not respond appropriately (As this seller did.), then when the burden of proof falls on the seller to show it was a mistake and not a sales gimmick, the buyer has an argument.
As for me, I think I'm done here. Not just here, but on the forum. At least for awhile. I see nonsense and it makes my blood pressure rise. My leaving is not having to do with others posting as I love to argue with the best. It has to do with me.
Merry Christmas or whatever non-secular season's greetings to all.
