Hello, stumped on a question regarding UCC 2-207. If a PO (offer) says, "this offer can be accepted only on the terms hereof and any response to this offer that contains additional or differing terms shall not constitute an acceptance hereof" and the purported acknowledgement (acceptance) says, "weaccept your offer. There shall be a one year warranty limited to replacement only on fencing" . Please note the PO doesn't say anything about a warranty.

Is there a contract under 2-207 (1)?
