In a couple of your posts, you've basically indicated that explicit language must be present within the eBay auction text in order for the responsibility of the delivery of goods to be transferred from the seller to the buyer because of the UCC.

Thanks for providing the link to a copy of the UCC. I have read that and have found an interesting clause in the UCC that I feel shoots a hole in your argument.

Of particular interest is § 1-302. Variation by Agreement.; subsection (a) which is quoted below:

(a) Except as otherwise provided in subsection (b) or elsewhere in [the Uniform Commercial Code], the effect of provisions of [the Uniform Commercial Code] may be varied by agreement.

The word "agreement" is hot-linked to it's UCC definition which is quoted below:

"Agreement", as distinguished from "contract", means the bargain of the parties in fact, as found in their language or inferred from other circumstances, including course of performance, course of dealing, or usage of trade as provided in Section 1-303.

And in case there is a question regarding the UCC's definition of contract, I've quote that below:

"Contract", as distinguished from "agreement", means the total legal obligation that results from the parties' agreement as determined by [the Uniform Commercial Code] as supplemented by any other applicable laws.

I've highlighted the passage of text in blue that was of interest to me. It indicates that variation by agreement can be obtained for the transaction by inferred circumstances. As a result, I do not believe explicit language has to be present in order for the transfer of that said responsibility from the seller to the buyer. It is my opinion that whenever the cost of insurance is taken out of the core shipping-and-handling charges and offered to the buyer as an optional component of the transaction, that infers a change in responsibility for the safe delivery of the goods in question from the seller to the buyer.
