disagrees with you. Too bad it was posted by an AC, someone could earn a bit of karma.
The Federal law (39 USC 3009) has precedence over state law, particularly with regards to interstate transactions; therefore, if the UCC is in disagreement, then the federal law wins.
The UCC is not law per se, but one revision or another has been adopted by each of the 50 states.
Anyways... the citation you linked to doesn't say anything about the Buyer having any liabilities it just lists some Buyer's rights; with respect to sales.
Again, the more-specific federal law, that lists more recipients' rights, wins.
