I ORDERED ONE OF THESE HEATED VESTS BEFORE, BUT WANT ANOTHER WITH THE BATTERY PACK...(JUST NOW ORDERED).... """""PLEASE, TRY TO GET IT HERE BY DEC. 24TH..."""".. I'M GETTING THIS FOR MY GRANDDAUGHTER WHO HAS TO CARE FOR HORSES IN THIS COLD WEATHER AND I WANT HER TO """"HAVE IT TO OPEN FOR CHRISTMAS MORNING"""". THANKS..... I WILL ORDER A BATTERY PACK AFTER THE FIRST OF THE YEAR FOR THIS ONE I ALREADY HAVE.....I DIDN'T KNOW IT WASN'T INCLUDED WHEN I ORDERED IT. (I'M KEEPING THIS ONE FOR MYSELF....AND CAN USE MY COMPUTER TO PLUG IT IN..AS I DON'T GO OUT MUCH)....I'M 83 AND THIS IS "DELIGHTFUL"!!!!! THANKS
