DOES the free shipping apply to this sale also?? I was going to place an order for 72.19 this morning but when it came time for shipping there was no option for it...just USPS and EXPRESS. I have not ordered anything since we have been offered free shipping so not sure if i am doing something wrong or if it is just not offered on this sale.any help would be appriciated as i plan to place my order either way!! CAN NT have too many batteries OR chargers can we????
