USPS, and others over sea's, Batts have a hazardous situation when shipping by air,,,, so they made a new ruling and as of May 16th I believe it is they will only be able to use Fed Ex, DSL, and maybe a couple other smaller companies, but there will be no more USPS and others shipping Batts over seas conan, so if your buying over seas rechargable and your low you may want to buy some now. This should also have an effect on pricing since all vendors will most likely have to pay more for shipping the way I see this, not a lot but some.
Thank you mwa102464 for the information!
