My bitchy local USPS clerk refused to accept my package with battery shipping to UK because of this new rules.
"Starting May 16, USPS will prohibit international mailing of lithium batteries and electronic devices containing lithium batteries. The new regulations also prohibit shipments to or from Army, Fleet and Diplomatic Post Offices...."
While heading back to my car, I read the notice that said starting May 16. Today is only May 14. I walked back. She has to accept my package! Ha! I won!
